Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72508, here are decompositions:

5 + 72503 = 72508
11 + 72497 = 72508
41 + 72467 = 72508
47 + 72461 = 72508
167 + 72341 = 72508
239 + 72269 = 72508
257 + 72251 = 72508
281 + 72227 = 72508

Showing the first eight; more decompositions exist.
