Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614640, here are decompositions:

  • 3 + 8614637 = 8614640
  • 31 + 8614609 = 8614640
  • 61 + 8614579 = 8614640
  • 79 + 8614561 = 8614640
  • 127 + 8614513 = 8614640
  • 157 + 8614483 = 8614640
  • 163 + 8614477 = 8614640
  • 271 + 8614369 = 8614640

Showing the first eight; more decompositions exist.
