Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986650, here are decompositions:

17 + 986633 = 986650
53 + 986597 = 986650
83 + 986567 = 986650
107 + 986543 = 986650
131 + 986519 = 986650
173 + 986477 = 986650
179 + 986471 = 986650
233 + 986417 = 986650

Showing the first eight; more decompositions exist.
