Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658656, here are decompositions:

3 + 8658653 = 8658656
37 + 8658619 = 8658656
43 + 8658613 = 8658656
67 + 8658589 = 8658656
73 + 8658583 = 8658656
79 + 8658577 = 8658656
103 + 8658553 = 8658656
163 + 8658493 = 8658656

Showing the first eight; more decompositions exist.
