Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688540, here are decompositions:

  • 13 + 8688527 = 8688540
  • 19 + 8688521 = 8688540
  • 43 + 8688497 = 8688540
  • 71 + 8688469 = 8688540
  • 103 + 8688437 = 8688540
  • 131 + 8688409 = 8688540
  • 191 + 8688349 = 8688540
  • 229 + 8688311 = 8688540

Showing the first eight; more decompositions exist.
