Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641460, here are decompositions:

  • 7 + 8641453 = 8641460
  • 31 + 8641429 = 8641460
  • 109 + 8641351 = 8641460
  • 151 + 8641309 = 8641460
  • 211 + 8641249 = 8641460
  • 229 + 8641231 = 8641460
  • 313 + 8641147 = 8641460
  • 367 + 8641093 = 8641460

Showing the first eight; more decompositions exist.
