Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588412, here are decompositions:

  • 13 + 31588399 = 31588412
  • 43 + 31588369 = 31588412
  • 61 + 31588351 = 31588412
  • 109 + 31588303 = 31588412
  • 211 + 31588201 = 31588412
  • 241 + 31588171 = 31588412
  • 283 + 31588129 = 31588412
  • 409 + 31588003 = 31588412

Showing the first eight; more decompositions exist.
