Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679816, here are decompositions:

  • 73 + 8679743 = 8679816
  • 107 + 8679709 = 8679816
  • 139 + 8679677 = 8679816
  • 199 + 8679617 = 8679816
  • 317 + 8679499 = 8679816
  • 359 + 8679457 = 8679816
  • 367 + 8679449 = 8679816
  • 389 + 8679427 = 8679816

Showing the first eight; more decompositions exist.
