Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556708, here are decompositions:

  • 61 + 31556647 = 31556708
  • 151 + 31556557 = 31556708
  • 229 + 31556479 = 31556708
  • 241 + 31556467 = 31556708
  • 367 + 31556341 = 31556708
  • 709 + 31555999 = 31556708
  • 727 + 31555981 = 31556708
  • 739 + 31555969 = 31556708

Showing the first eight; more decompositions exist.
