Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627352, here are decompositions:

  • 19 + 31627333 = 31627352
  • 103 + 31627249 = 31627352
  • 109 + 31627243 = 31627352
  • 151 + 31627201 = 31627352
  • 283 + 31627069 = 31627352
  • 373 + 31626979 = 31627352
  • 409 + 31626943 = 31627352
  • 643 + 31626709 = 31627352

Showing the first eight; more decompositions exist.
