Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537110, here are decompositions:

  • 13 + 31537097 = 31537110
  • 23 + 31537087 = 31537110
  • 61 + 31537049 = 31537110
  • 67 + 31537043 = 31537110
  • 71 + 31537039 = 31537110
  • 83 + 31537027 = 31537110
  • 107 + 31537003 = 31537110
  • 109 + 31537001 = 31537110

Showing the first eight; more decompositions exist.
