Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627082, here are decompositions:

  • 13 + 31627069 = 31627082
  • 31 + 31627051 = 31627082
  • 103 + 31626979 = 31627082
  • 139 + 31626943 = 31627082
  • 199 + 31626883 = 31627082
  • 241 + 31626841 = 31627082
  • 373 + 31626709 = 31627082
  • 463 + 31626619 = 31627082

Showing the first eight; more decompositions exist.
