Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986620, here are decompositions:

3 + 986617 = 986620
23 + 986597 = 986620
53 + 986567 = 986620
101 + 986519 = 986620
113 + 986507 = 986620
149 + 986471 = 986620
191 + 986429 = 986620
251 + 986369 = 986620

Showing the first eight; more decompositions exist.
