Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986666, here are decompositions:

7 + 986659 = 986666
67 + 986599 = 986666
73 + 986593 = 986666
97 + 986569 = 986666
103 + 986563 = 986666
157 + 986509 = 986666
229 + 986437 = 986666
379 + 986287 = 986666

Showing the first eight; more decompositions exist.
