Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626850, here are decompositions:

  • 11 + 31626839 = 31626850
  • 23 + 31626827 = 31626850
  • 53 + 31626797 = 31626850
  • 83 + 31626767 = 31626850
  • 293 + 31626557 = 31626850
  • 317 + 31626533 = 31626850
  • 389 + 31626461 = 31626850
  • 443 + 31626407 = 31626850

Showing the first eight; more decompositions exist.
