Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676844, here are decompositions:

  • 17 + 8676827 = 8676844
  • 23 + 8676821 = 8676844
  • 101 + 8676743 = 8676844
  • 257 + 8676587 = 8676844
  • 311 + 8676533 = 8676844
  • 317 + 8676527 = 8676844
  • 443 + 8676401 = 8676844
  • 461 + 8676383 = 8676844

Showing the first eight; more decompositions exist.
