Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637768, here are decompositions:

  • 19 + 8637749 = 8637768
  • 67 + 8637701 = 8637768
  • 71 + 8637697 = 8637768
  • 101 + 8637667 = 8637768
  • 127 + 8637641 = 8637768
  • 131 + 8637637 = 8637768
  • 149 + 8637619 = 8637768
  • 151 + 8637617 = 8637768

Showing the first eight; more decompositions exist.
