Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56540, here are decompositions:

  • 7 + 56533 = 56540
  • 13 + 56527 = 56540
  • 31 + 56509 = 56540
  • 37 + 56503 = 56540
  • 61 + 56479 = 56540
  • 67 + 56473 = 56540
  • 73 + 56467 = 56540
  • 97 + 56443 = 56540

Showing the first eight; more decompositions exist.
