Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72328, here are decompositions:

  • 41 + 72287 = 72328
  • 59 + 72269 = 72328
  • 101 + 72227 = 72328
  • 107 + 72221 = 72328
  • 167 + 72161 = 72328
  • 227 + 72101 = 72328
  • 239 + 72089 = 72328
  • 251 + 72077 = 72328

Showing the first eight; more decompositions exist.
