Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180304, here are decompositions:

17 + 180287 = 180304
23 + 180281 = 180304
41 + 180263 = 180304
71 + 180233 = 180304
83 + 180221 = 180304
167 + 180137 = 180304
227 + 180077 = 180304
233 + 180071 = 180304

Showing the first eight; more decompositions exist.
