Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638822, here are decompositions:

  • 89 + 8638733 = 8638822
  • 131 + 8638691 = 8638822
  • 239 + 8638583 = 8638822
  • 359 + 8638463 = 8638822
  • 419 + 8638403 = 8638822
  • 443 + 8638379 = 8638822
  • 449 + 8638373 = 8638822
  • 503 + 8638319 = 8638822

Showing the first eight; more decompositions exist.
