Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542796, here are decompositions:

  • 29 + 31542767 = 31542796
  • 137 + 31542659 = 31542796
  • 317 + 31542479 = 31542796
  • 359 + 31542437 = 31542796
  • 419 + 31542377 = 31542796
  • 563 + 31542233 = 31542796
  • 599 + 31542197 = 31542796
  • 647 + 31542149 = 31542796

Showing the first eight; more decompositions exist.
