Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596976, here are decompositions:

  • 53 + 31596923 = 31596976
  • 137 + 31596839 = 31596976
  • 179 + 31596797 = 31596976
  • 227 + 31596749 = 31596976
  • 233 + 31596743 = 31596976
  • 263 + 31596713 = 31596976
  • 269 + 31596707 = 31596976
  • 479 + 31596497 = 31596976

Showing the first eight; more decompositions exist.
