Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72238, here are decompositions:

11 + 72227 = 72238
17 + 72221 = 72238
71 + 72167 = 72238
137 + 72101 = 72238
149 + 72089 = 72238
191 + 72047 = 72238
239 + 71999 = 72238
251 + 71987 = 72238

Showing the first eight; more decompositions exist.
