Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529944, here are decompositions:

  • 11 + 31529933 = 31529944
  • 53 + 31529891 = 31529944
  • 101 + 31529843 = 31529944
  • 227 + 31529717 = 31529944
  • 263 + 31529681 = 31529944
  • 293 + 31529651 = 31529944
  • 701 + 31529243 = 31529944
  • 857 + 31529087 = 31529944

Showing the first eight; more decompositions exist.
