Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545814, here are decompositions:

  • 71 + 31545743 = 31545814
  • 101 + 31545713 = 31545814
  • 173 + 31545641 = 31545814
  • 191 + 31545623 = 31545814
  • 491 + 31545323 = 31545814
  • 593 + 31545221 = 31545814
  • 1031 + 31544783 = 31545814
  • 1097 + 31544717 = 31545814

Showing the first eight; more decompositions exist.
