Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986586, here are decompositions:

5 + 986581 = 986586
17 + 986569 = 986586
19 + 986567 = 986586
23 + 986563 = 986586
43 + 986543 = 986586
53 + 986533 = 986586
67 + 986519 = 986586
79 + 986507 = 986586

Showing the first eight; more decompositions exist.
