Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617726, here are decompositions:

  • 13 + 31617713 = 31617726
  • 29 + 31617697 = 31617726
  • 37 + 31617689 = 31617726
  • 47 + 31617679 = 31617726
  • 53 + 31617673 = 31617726
  • 59 + 31617667 = 31617726
  • 67 + 31617659 = 31617726
  • 97 + 31617629 = 31617726

Showing the first eight; more decompositions exist.
