Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986538, here are decompositions:

5 + 986533 = 986538
19 + 986519 = 986538
29 + 986509 = 986538
31 + 986507 = 986538
41 + 986497 = 986538
61 + 986477 = 986538
67 + 986471 = 986538
101 + 986437 = 986538

Showing the first eight; more decompositions exist.
