Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678656, here are decompositions:

  • 17 + 8678639 = 8678656
  • 53 + 8678603 = 8678656
  • 137 + 8678519 = 8678656
  • 149 + 8678507 = 8678656
  • 257 + 8678399 = 8678656
  • 263 + 8678393 = 8678656
  • 293 + 8678363 = 8678656
  • 317 + 8678339 = 8678656

Showing the first eight; more decompositions exist.
