Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56560, here are decompositions:

  • 17 + 56543 = 56560
  • 29 + 56531 = 56560
  • 41 + 56519 = 56560
  • 59 + 56501 = 56560
  • 71 + 56489 = 56560
  • 83 + 56477 = 56560
  • 107 + 56453 = 56560
  • 167 + 56393 = 56560

Showing the first eight; more decompositions exist.
