Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545092, here are decompositions:

  • 31 + 31545061 = 31545092
  • 43 + 31545049 = 31545092
  • 151 + 31544941 = 31545092
  • 193 + 31544899 = 31545092
  • 373 + 31544719 = 31545092
  • 379 + 31544713 = 31545092
  • 541 + 31544551 = 31545092
  • 769 + 31544323 = 31545092

Showing the first eight; more decompositions exist.
