Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735640, here are decompositions:

  • 7 + 8735633 = 8735640
  • 19 + 8735621 = 8735640
  • 31 + 8735609 = 8735640
  • 59 + 8735581 = 8735640
  • 83 + 8735557 = 8735640
  • 103 + 8735537 = 8735640
  • 131 + 8735509 = 8735640
  • 191 + 8735449 = 8735640

Showing the first eight; more decompositions exist.
