Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986816, here are decompositions:

3 + 986813 = 986816
37 + 986779 = 986816
67 + 986749 = 986816
79 + 986737 = 986816
97 + 986719 = 986816
109 + 986707 = 986816
157 + 986659 = 986816
199 + 986617 = 986816

Showing the first eight; more decompositions exist.
