Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517234, here are decompositions:

  • 3 + 31517231 = 31517234
  • 37 + 31517197 = 31517234
  • 223 + 31517011 = 31517234
  • 241 + 31516993 = 31517234
  • 283 + 31516951 = 31517234
  • 457 + 31516777 = 31517234
  • 601 + 31516633 = 31517234
  • 607 + 31516627 = 31517234

Showing the first eight; more decompositions exist.
