Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669656, here are decompositions:

5 + 8669651 = 8669656
29 + 8669627 = 8669656
113 + 8669543 = 8669656
167 + 8669489 = 8669656
173 + 8669483 = 8669656
179 + 8669477 = 8669656
239 + 8669417 = 8669656
257 + 8669399 = 8669656

Showing the first eight; more decompositions exist.
