Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489502, here are decompositions:

  • 13 + 31489489 = 31489502
  • 103 + 31489399 = 31489502
  • 139 + 31489363 = 31489502
  • 223 + 31489279 = 31489502
  • 433 + 31489069 = 31489502
  • 439 + 31489063 = 31489502
  • 523 + 31488979 = 31489502
  • 571 + 31488931 = 31489502

Showing the first eight; more decompositions exist.
