    Does anybody know if there's a link between Goldbach's conjecture and the Riemann hypothesis? I mean, imagine there's a connection that asserts that Goldbach's conjecture implies Riemann hypothesis :)))

  • @martinepstein9826

    Relating to Brady's question: Do the primes appear to be a minimal set for generating all even numbers > 4 by adding two elements? If not, what primes can we skip and still get sums for the even numbers calculated so far?

    • @martinepstein9826
      @martinepstein9826 7 лет назад +1

      The numbers 3, 5, and 7 are necessary because 6 = 3 + 3 and 12 = 5 + 7 are the only possible sums for 6 and 12. A commenter on the 210 video claims that 12 is the largest known even number with only one sum. This implies that as far as we know the Goldbach conjecture is still true for the set of prime numbers \ {11}, since if every even number > 12 has at least two sums then they have at least one sum that doesn't use 11. So I'd like to know the next prime we can eliminate after eliminating 11.

    Could there exist mathematical truths that cannot be proven? If so, could that statement itself be proven to be true? If not, could it be proven to be false? (Don't say "axioms".)

    From which even number on can even numbers be expressed as two distinct primes? Let's see.
    2 NO
    4 = 2+2 but those are not distinct so NO
    6=3+3 so NO
    8=3+5 YES.
    Will this keep going let's see.
    10=3+7 YES
    12=5+7 YES
    14=3+11 YES
    16=5+11 YES
    18=7+11 YES
    20=3+17 YES
    22=5+17 YES
    24=5+19 YES
    It seems to go on forever can somebody prove to me that an even number above 6 can always be expressed as two distinct primes? TY

      You can equate goldbach's conjecture to every number greater than some value, is equidistant from two primes. Furthermore, the twin prime conjecturecan be restated as 6m-1,6m+1 is a goldbach partition of 12m infinitely often. The statement about two primes being a certain even number apart can be turned to general statements about goldbach partitions.

    Why did he correct himself with 'arbitrarily many primes' instead of just saying 'infinitely many primes' at 3:09? Is there a difference?

    • @LeoMRogers
      @LeoMRogers 7 лет назад +3

      I think the difference is that no individual arithmetic progression necessarily has an infinite number of primes, but there is no limit on how many there can be in one.

    • @hexameron8603
      @hexameron8603 7 лет назад +3

      Yes, I think so. Infinitely many primes in an arithmetic progression would mean that every arithmetic progression has infinitely many primes, which is false (2,4,6,8,10,...). Arbitrarily many primes in an arithmetic progression means that for any number k you can find an arithmetic progression with more than k primes. (Edit: too late :/)
