Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986628, here are decompositions:

11 + 986617 = 986628
29 + 986599 = 986628
31 + 986597 = 986628
47 + 986581 = 986628
59 + 986569 = 986628
61 + 986567 = 986628
109 + 986519 = 986628
131 + 986497 = 986628

Showing the first eight; more decompositions exist.
