Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717120, here are decompositions:

  • 3 + 8717117 = 8717120
  • 7 + 8717113 = 8717120
  • 79 + 8717041 = 8717120
  • 109 + 8717011 = 8717120
  • 163 + 8716957 = 8717120
  • 229 + 8716891 = 8717120
  • 277 + 8716843 = 8717120
  • 337 + 8716783 = 8717120

Showing the first eight; more decompositions exist.
