Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640764, here are decompositions:

  • 3 + 8640761 = 8640764
  • 31 + 8640733 = 8640764
  • 61 + 8640703 = 8640764
  • 73 + 8640691 = 8640764
  • 163 + 8640601 = 8640764
  • 211 + 8640553 = 8640764
  • 271 + 8640493 = 8640764
  • 283 + 8640481 = 8640764

Showing the first eight; more decompositions exist.
