Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39618, here are decompositions:

11 + 39607 = 39618
37 + 39581 = 39618
67 + 39551 = 39618
97 + 39521 = 39618
107 + 39511 = 39618
109 + 39509 = 39618
157 + 39461 = 39618
167 + 39451 = 39618

Showing the first eight; more decompositions exist.
