Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545066, here are decompositions:

  • 5 + 31545061 = 31545066
  • 17 + 31545049 = 31545066
  • 43 + 31545023 = 31545066
  • 97 + 31544969 = 31545066
  • 103 + 31544963 = 31545066
  • 167 + 31544899 = 31545066
  • 239 + 31544827 = 31545066
  • 283 + 31544783 = 31545066

Showing the first eight; more decompositions exist.
