Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495388, here are decompositions:

  • 11 + 495377 = 495388
  • 17 + 495371 = 495388
  • 29 + 495359 = 495388
  • 41 + 495347 = 495388
  • 167 + 495221 = 495388
  • 227 + 495161 = 495388
  • 239 + 495149 = 495388
  • 269 + 495119 = 495388

Showing the first eight; more decompositions exist.
