Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494908, here are decompositions:

  • 127 + 31494781 = 31494908
  • 139 + 31494769 = 31494908
  • 229 + 31494679 = 31494908
  • 271 + 31494637 = 31494908
  • 439 + 31494469 = 31494908
  • 607 + 31494301 = 31494908
  • 661 + 31494247 = 31494908
  • 751 + 31494157 = 31494908

Showing the first eight; more decompositions exist.
