Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72612, here are decompositions:

53 + 72559 = 72612
61 + 72551 = 72612
79 + 72533 = 72612
109 + 72503 = 72612
131 + 72481 = 72612
151 + 72461 = 72612
181 + 72431 = 72612
191 + 72421 = 72612

Showing the first eight; more decompositions exist.
