Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617456, here are decompositions:

  • 7 + 31617449 = 31617456
  • 43 + 31617413 = 31617456
  • 47 + 31617409 = 31617456
  • 53 + 31617403 = 31617456
  • 83 + 31617373 = 31617456
  • 127 + 31617329 = 31617456
  • 163 + 31617293 = 31617456
  • 173 + 31617283 = 31617456

Showing the first eight; more decompositions exist.
