Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72526, here are decompositions:

23 + 72503 = 72526
29 + 72497 = 72526
59 + 72467 = 72526
173 + 72353 = 72526
239 + 72287 = 72526
257 + 72269 = 72526
353 + 72173 = 72526
359 + 72167 = 72526

Showing the first eight; more decompositions exist.
