Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576744, here are decompositions:

  • 5 + 31576739 = 31576744
  • 41 + 31576703 = 31576744
  • 71 + 31576673 = 31576744
  • 233 + 31576511 = 31576744
  • 317 + 31576427 = 31576744
  • 461 + 31576283 = 31576744
  • 491 + 31576253 = 31576744
  • 503 + 31576241 = 31576744

Showing the first eight; more decompositions exist.
