Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603638, here are decompositions:

41 + 8603597 = 8603638
47 + 8603591 = 8603638
59 + 8603579 = 8603638
149 + 8603489 = 8603638
167 + 8603471 = 8603638
257 + 8603381 = 8603638
269 + 8603369 = 8603638
389 + 8603249 = 8603638

Showing the first eight; more decompositions exist.
