Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638736, here are decompositions:

  • 3 + 8638733 = 8638736
  • 103 + 8638633 = 8638736
  • 109 + 8638627 = 8638736
  • 193 + 8638543 = 8638736
  • 283 + 8638453 = 8638736
  • 397 + 8638339 = 8638736
  • 409 + 8638327 = 8638736
  • 499 + 8638237 = 8638736

Showing the first eight; more decompositions exist.
