Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72340, here are decompositions:

3 + 72337 = 72340
53 + 72287 = 72340
71 + 72269 = 72340
89 + 72251 = 72340
113 + 72227 = 72340
167 + 72173 = 72340
173 + 72167 = 72340
179 + 72161 = 72340

Showing the first eight; more decompositions exist.
