Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545132, here are decompositions:

  • 13 + 31545119 = 31545132
  • 41 + 31545091 = 31545132
  • 71 + 31545061 = 31545132
  • 83 + 31545049 = 31545132
  • 109 + 31545023 = 31545132
  • 131 + 31545001 = 31545132
  • 163 + 31544969 = 31545132
  • 191 + 31544941 = 31545132

Showing the first eight; more decompositions exist.
