Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617640, here are decompositions:

  • 11 + 33617629 = 33617640
  • 19 + 33617621 = 33617640
  • 29 + 33617611 = 33617640
  • 37 + 33617603 = 33617640
  • 41 + 33617599 = 33617640
  • 79 + 33617561 = 33617640
  • 83 + 33617557 = 33617640
  • 97 + 33617543 = 33617640

Showing the first eight; more decompositions exist.
