Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718040, here are decompositions:

  • 29 + 8718011 = 8718040
  • 41 + 8717999 = 8718040
  • 47 + 8717993 = 8718040
  • 53 + 8717987 = 8718040
  • 59 + 8717981 = 8718040
  • 101 + 8717939 = 8718040
  • 113 + 8717927 = 8718040
  • 131 + 8717909 = 8718040

Showing the first eight; more decompositions exist.
