Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679636, here are decompositions:

  • 19 + 8679617 = 8679636
  • 29 + 8679607 = 8679636
  • 79 + 8679557 = 8679636
  • 107 + 8679529 = 8679636
  • 109 + 8679527 = 8679636
  • 137 + 8679499 = 8679636
  • 179 + 8679457 = 8679636
  • 239 + 8679397 = 8679636

Showing the first eight; more decompositions exist.
