Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72514, here are decompositions:

11 + 72503 = 72514
17 + 72497 = 72514
47 + 72467 = 72514
53 + 72461 = 72514
83 + 72431 = 72514
131 + 72383 = 72514
173 + 72341 = 72514
227 + 72287 = 72514

Showing the first eight; more decompositions exist.
