Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676640, here are decompositions:

  • 53 + 8676587 = 8676640
  • 107 + 8676533 = 8676640
  • 113 + 8676527 = 8676640
  • 173 + 8676467 = 8676640
  • 191 + 8676449 = 8676640
  • 239 + 8676401 = 8676640
  • 257 + 8676383 = 8676640
  • 263 + 8676377 = 8676640

Showing the first eight; more decompositions exist.
