Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986660, here are decompositions:

19 + 986641 = 986660
43 + 986617 = 986660
61 + 986599 = 986660
67 + 986593 = 986660
79 + 986581 = 986660
97 + 986563 = 986660
127 + 986533 = 986660
151 + 986509 = 986660

Showing the first eight; more decompositions exist.
