Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624850, here are decompositions:

  • 13 + 31624837 = 31624850
  • 43 + 31624807 = 31624850
  • 67 + 31624783 = 31624850
  • 97 + 31624753 = 31624850
  • 109 + 31624741 = 31624850
  • 151 + 31624699 = 31624850
  • 211 + 31624639 = 31624850
  • 223 + 31624627 = 31624850

Showing the first eight; more decompositions exist.
