Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682720, here are decompositions:

  • 19 + 8682701 = 8682720
  • 29 + 8682691 = 8682720
  • 61 + 8682659 = 8682720
  • 131 + 8682589 = 8682720
  • 227 + 8682493 = 8682720
  • 239 + 8682481 = 8682720
  • 283 + 8682437 = 8682720
  • 307 + 8682413 = 8682720

Showing the first eight; more decompositions exist.
