Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639762, here are decompositions:

  • 13 + 8639749 = 8639762
  • 163 + 8639599 = 8639762
  • 199 + 8639563 = 8639762
  • 211 + 8639551 = 8639762
  • 223 + 8639539 = 8639762
  • 349 + 8639413 = 8639762
  • 463 + 8639299 = 8639762
  • 499 + 8639263 = 8639762

Showing the first eight; more decompositions exist.
