Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543718, here are decompositions:

  • 7 + 31543711 = 31543718
  • 139 + 31543579 = 31543718
  • 229 + 31543489 = 31543718
  • 487 + 31543231 = 31543718
  • 499 + 31543219 = 31543718
  • 709 + 31543009 = 31543718
  • 727 + 31542991 = 31543718
  • 751 + 31542967 = 31543718

Showing the first eight; more decompositions exist.
