Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72418, here are decompositions:

131 + 72287 = 72418
149 + 72269 = 72418
167 + 72251 = 72418
191 + 72227 = 72418
197 + 72221 = 72418
251 + 72167 = 72418
257 + 72161 = 72418
317 + 72101 = 72418

Showing the first eight; more decompositions exist.
