Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627892, here are decompositions:

  • 3 + 31627889 = 31627892
  • 13 + 31627879 = 31627892
  • 31 + 31627861 = 31627892
  • 139 + 31627753 = 31627892
  • 349 + 31627543 = 31627892
  • 409 + 31627483 = 31627892
  • 631 + 31627261 = 31627892
  • 643 + 31627249 = 31627892

Showing the first eight; more decompositions exist.
