Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669646, here are decompositions:

17 + 8669629 = 8669646
19 + 8669627 = 8669646
23 + 8669623 = 8669646
53 + 8669593 = 8669646
103 + 8669543 = 8669646
157 + 8669489 = 8669646
163 + 8669483 = 8669646
199 + 8669447 = 8669646

Showing the first eight; more decompositions exist.
