Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568704, here are decompositions:

  • 3 + 31568701 = 31568704
  • 47 + 31568657 = 31568704
  • 281 + 31568423 = 31568704
  • 311 + 31568393 = 31568704
  • 317 + 31568387 = 31568704
  • 347 + 31568357 = 31568704
  • 617 + 31568087 = 31568704
  • 677 + 31568027 = 31568704

Showing the first eight; more decompositions exist.
