Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667540, here are decompositions:

  • 19 + 8667521 = 8667540
  • 29 + 8667511 = 8667540
  • 43 + 8667497 = 8667540
  • 83 + 8667457 = 8667540
  • 109 + 8667431 = 8667540
  • 113 + 8667427 = 8667540
  • 127 + 8667413 = 8667540
  • 137 + 8667403 = 8667540

Showing the first eight; more decompositions exist.
