Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72624, here are decompositions:

7 + 72617 = 72624
11 + 72613 = 72624
47 + 72577 = 72624
73 + 72551 = 72624
127 + 72497 = 72624
131 + 72493 = 72624
157 + 72467 = 72624
163 + 72461 = 72624

Showing the first eight; more decompositions exist.
