Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 322, here are decompositions:

5 + 317 = 322
11 + 311 = 322
29 + 293 = 322
41 + 281 = 322
53 + 269 = 322
59 + 263 = 322
71 + 251 = 322
83 + 239 = 322

Showing the first eight; more decompositions exist.
