Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72636, here are decompositions:

13 + 72623 = 72636
19 + 72617 = 72636
23 + 72613 = 72636
59 + 72577 = 72636
89 + 72547 = 72636
103 + 72533 = 72636
139 + 72497 = 72636
167 + 72469 = 72636

Showing the first eight; more decompositions exist.
