Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603628, here are decompositions:

17 + 8603611 = 8603628
31 + 8603597 = 8603628
37 + 8603591 = 8603628
107 + 8603521 = 8603628
139 + 8603489 = 8603628
151 + 8603477 = 8603628
157 + 8603471 = 8603628
199 + 8603429 = 8603628

Showing the first eight; more decompositions exist.
