Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528068, here are decompositions:

  • 31 + 31528037 = 31528068
  • 67 + 31528001 = 31528068
  • 71 + 31527997 = 31528068
  • 101 + 31527967 = 31528068
  • 127 + 31527941 = 31528068
  • 137 + 31527931 = 31528068
  • 181 + 31527887 = 31528068
  • 239 + 31527829 = 31528068

Showing the first eight; more decompositions exist.
