Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42320, here are decompositions:

  • 13 + 42307 = 42320
  • 37 + 42283 = 42320
  • 97 + 42223 = 42320
  • 127 + 42193 = 42320
  • 139 + 42181 = 42320
  • 151 + 42169 = 42320
  • 163 + 42157 = 42320
  • 181 + 42139 = 42320

Showing the first eight; more decompositions exist.
