Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986636, here are decompositions:

3 + 986633 = 986636
19 + 986617 = 986636
37 + 986599 = 986636
43 + 986593 = 986636
67 + 986569 = 986636
73 + 986563 = 986636
103 + 986533 = 986636
127 + 986509 = 986636

Showing the first eight; more decompositions exist.
