Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86560, here are decompositions:

  • 29 + 86531 = 86560
  • 59 + 86501 = 86560
  • 83 + 86477 = 86560
  • 107 + 86453 = 86560
  • 137 + 86423 = 86560
  • 179 + 86381 = 86560
  • 191 + 86369 = 86560
  • 263 + 86297 = 86560

Showing the first eight; more decompositions exist.
