Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626650, here are decompositions:

  • 31 + 31626619 = 31626650
  • 43 + 31626607 = 31626650
  • 61 + 31626589 = 31626650
  • 79 + 31626571 = 31626650
  • 103 + 31626547 = 31626650
  • 151 + 31626499 = 31626650
  • 157 + 31626493 = 31626650
  • 229 + 31626421 = 31626650

Showing the first eight; more decompositions exist.
