Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86736, here are decompositions:

  • 7 + 86729 = 86736
  • 17 + 86719 = 86736
  • 43 + 86693 = 86736
  • 47 + 86689 = 86736
  • 59 + 86677 = 86736
  • 107 + 86629 = 86736
  • 109 + 86627 = 86736
  • 137 + 86599 = 86736

Showing the first eight; more decompositions exist.
