Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617646, here are decompositions:

  • 17 + 31617629 = 31617646
  • 59 + 31617587 = 31617646
  • 83 + 31617563 = 31617646
  • 113 + 31617533 = 31617646
  • 149 + 31617497 = 31617646
  • 197 + 31617449 = 31617646
  • 233 + 31617413 = 31617646
  • 239 + 31617407 = 31617646

Showing the first eight; more decompositions exist.
