Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86816, here are decompositions:

  • 3 + 86813 = 86816
  • 73 + 86743 = 86816
  • 97 + 86719 = 86816
  • 127 + 86689 = 86816
  • 139 + 86677 = 86816
  • 229 + 86587 = 86816
  • 277 + 86539 = 86816
  • 283 + 86533 = 86816

Showing the first eight; more decompositions exist.
