Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986518, here are decompositions:

11 + 986507 = 986518
41 + 986477 = 986518
47 + 986471 = 986518
89 + 986429 = 986518
101 + 986417 = 986518
107 + 986411 = 986518
149 + 986369 = 986518
167 + 986351 = 986518

Showing the first eight; more decompositions exist.
