Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617976, here are decompositions:

  • 17 + 31617959 = 31617976
  • 23 + 31617953 = 31617976
  • 113 + 31617863 = 31617976
  • 149 + 31617827 = 31617976
  • 179 + 31617797 = 31617976
  • 263 + 31617713 = 31617976
  • 317 + 31617659 = 31617976
  • 347 + 31617629 = 31617976

Showing the first eight; more decompositions exist.
