Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722310, here are decompositions:

  • 7 + 8722303 = 8722310
  • 13 + 8722297 = 8722310
  • 19 + 8722291 = 8722310
  • 73 + 8722237 = 8722310
  • 139 + 8722171 = 8722310
  • 193 + 8722117 = 8722310
  • 211 + 8722099 = 8722310
  • 229 + 8722081 = 8722310

Showing the first eight; more decompositions exist.
