Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617904, here are decompositions:

  • 5 + 31617899 = 31617904
  • 41 + 31617863 = 31617904
  • 107 + 31617797 = 31617904
  • 191 + 31617713 = 31617904
  • 317 + 31617587 = 31617904
  • 401 + 31617503 = 31617904
  • 443 + 31617461 = 31617904
  • 491 + 31617413 = 31617904

Showing the first eight; more decompositions exist.
