Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627746, here are decompositions:

  • 19 + 31627727 = 31627746
  • 97 + 31627649 = 31627746
  • 107 + 31627639 = 31627746
  • 173 + 31627573 = 31627746
  • 179 + 31627567 = 31627746
  • 263 + 31627483 = 31627746
  • 373 + 31627373 = 31627746
  • 389 + 31627357 = 31627746

Showing the first eight; more decompositions exist.
