Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64320, here are decompositions:

  • 17 + 64303 = 64320
  • 19 + 64301 = 64320
  • 37 + 64283 = 64320
  • 41 + 64279 = 64320
  • 83 + 64237 = 64320
  • 89 + 64231 = 64320
  • 97 + 64223 = 64320
  • 103 + 64217 = 64320

Showing the first eight; more decompositions exist.
