Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603668, here are decompositions:

5 + 8603663 = 8603668
11 + 8603657 = 8603668
71 + 8603597 = 8603668
89 + 8603579 = 8603668
179 + 8603489 = 8603668
191 + 8603477 = 8603668
197 + 8603471 = 8603668
239 + 8603429 = 8603668

Showing the first eight; more decompositions exist.
