Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65800, here are decompositions:

  • 11 + 65789 = 65800
  • 23 + 65777 = 65800
  • 71 + 65729 = 65800
  • 83 + 65717 = 65800
  • 101 + 65699 = 65800
  • 113 + 65687 = 65800
  • 149 + 65651 = 65800
  • 167 + 65633 = 65800

Showing the first eight; more decompositions exist.
