Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65700, here are decompositions:

  • 13 + 65687 = 65700
  • 23 + 65677 = 65700
  • 43 + 65657 = 65700
  • 53 + 65647 = 65700
  • 67 + 65633 = 65700
  • 71 + 65629 = 65700
  • 83 + 65617 = 65700
  • 101 + 65599 = 65700

Showing the first eight; more decompositions exist.
