Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640982, here are decompositions:

  • 5 + 8640977 = 8640982
  • 71 + 8640911 = 8640982
  • 263 + 8640719 = 8640982
  • 269 + 8640713 = 8640982
  • 281 + 8640701 = 8640982
  • 293 + 8640689 = 8640982
  • 479 + 8640503 = 8640982
  • 563 + 8640419 = 8640982

Showing the first eight; more decompositions exist.
