Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72658, here are decompositions:

11 + 72647 = 72658
41 + 72617 = 72658
107 + 72551 = 72658
191 + 72467 = 72658
197 + 72461 = 72658
227 + 72431 = 72658
317 + 72341 = 72658
389 + 72269 = 72658

Showing the first eight; more decompositions exist.
