Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594800, here are decompositions:

  • 31 + 31594769 = 31594800
  • 43 + 31594757 = 31594800
  • 53 + 31594747 = 31594800
  • 71 + 31594729 = 31594800
  • 73 + 31594727 = 31594800
  • 101 + 31594699 = 31594800
  • 109 + 31594691 = 31594800
  • 173 + 31594627 = 31594800

Showing the first eight; more decompositions exist.
