Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986656, here are decompositions:

23 + 986633 = 986656
59 + 986597 = 986656
89 + 986567 = 986656
113 + 986543 = 986656
137 + 986519 = 986656
149 + 986507 = 986656
179 + 986477 = 986656
227 + 986429 = 986656

Showing the first eight; more decompositions exist.
