Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72556, here are decompositions:

5 + 72551 = 72556
23 + 72533 = 72556
53 + 72503 = 72556
59 + 72497 = 72556
89 + 72467 = 72556
173 + 72383 = 72556
269 + 72287 = 72556
383 + 72173 = 72556

Showing the first eight; more decompositions exist.
