Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18224, here are decompositions:

  • 7 + 18217 = 18224
  • 13 + 18211 = 18224
  • 43 + 18181 = 18224
  • 97 + 18127 = 18224
  • 103 + 18121 = 18224
  • 127 + 18097 = 18224
  • 163 + 18061 = 18224
  • 181 + 18043 = 18224

Showing the first eight; more decompositions exist.
