Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627226, here are decompositions:

  • 157 + 31627069 = 31627226
  • 193 + 31627033 = 31627226
  • 199 + 31627027 = 31627226
  • 283 + 31626943 = 31627226
  • 439 + 31626787 = 31627226
  • 607 + 31626619 = 31627226
  • 619 + 31626607 = 31627226
  • 727 + 31626499 = 31627226

Showing the first eight; more decompositions exist.
