Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528110, here are decompositions:

  • 7 + 31528103 = 31528110
  • 17 + 31528093 = 31528110
  • 41 + 31528069 = 31528110
  • 43 + 31528067 = 31528110
  • 73 + 31528037 = 31528110
  • 109 + 31528001 = 31528110
  • 113 + 31527997 = 31528110
  • 179 + 31527931 = 31528110

Showing the first eight; more decompositions exist.
