Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626672, here are decompositions:

  • 5 + 31626667 = 31626672
  • 53 + 31626619 = 31626672
  • 83 + 31626589 = 31626672
  • 101 + 31626571 = 31626672
  • 109 + 31626563 = 31626672
  • 139 + 31626533 = 31626672
  • 173 + 31626499 = 31626672
  • 179 + 31626493 = 31626672

Showing the first eight; more decompositions exist.
