Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627756, here are decompositions:

  • 3 + 31627753 = 31627756
  • 5 + 31627751 = 31627756
  • 29 + 31627727 = 31627756
  • 107 + 31627649 = 31627756
  • 179 + 31627577 = 31627756
  • 197 + 31627559 = 31627756
  • 383 + 31627373 = 31627756
  • 467 + 31627289 = 31627756

Showing the first eight; more decompositions exist.
