Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625656, here are decompositions:

7 + 8625649 = 8625656
19 + 8625637 = 8625656
97 + 8625559 = 8625656
103 + 8625553 = 8625656
139 + 8625517 = 8625656
163 + 8625493 = 8625656
307 + 8625349 = 8625656
313 + 8625343 = 8625656

Showing the first eight; more decompositions exist.
