Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528518, here are decompositions:

  • 17 + 31528501 = 31528518
  • 19 + 31528499 = 31528518
  • 59 + 31528459 = 31528518
  • 67 + 31528451 = 31528518
  • 71 + 31528447 = 31528518
  • 181 + 31528337 = 31528518
  • 191 + 31528327 = 31528518
  • 227 + 31528291 = 31528518

Showing the first eight; more decompositions exist.
