Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638846, here are decompositions:

  • 3 + 8638843 = 8638846
  • 113 + 8638733 = 8638846
  • 149 + 8638697 = 8638846
  • 263 + 8638583 = 8638846
  • 383 + 8638463 = 8638846
  • 389 + 8638457 = 8638846
  • 443 + 8638403 = 8638846
  • 467 + 8638379 = 8638846

Showing the first eight; more decompositions exist.
