Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545416, here are decompositions:

  • 37 + 31545379 = 31545416
  • 43 + 31545373 = 31545416
  • 73 + 31545343 = 31545416
  • 349 + 31545067 = 31545416
  • 367 + 31545049 = 31545416
  • 829 + 31544587 = 31545416
  • 883 + 31544533 = 31545416
  • 907 + 31544509 = 31545416

Showing the first eight; more decompositions exist.
