Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986658, here are decompositions:

17 + 986641 = 986658
41 + 986617 = 986658
59 + 986599 = 986658
61 + 986597 = 986658
89 + 986569 = 986658
139 + 986519 = 986658
149 + 986509 = 986658
151 + 986507 = 986658

Showing the first eight; more decompositions exist.
