Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986512, here are decompositions:

3 + 986509 = 986512
5 + 986507 = 986512
41 + 986471 = 986512
83 + 986429 = 986512
101 + 986411 = 986512
173 + 986339 = 986512
179 + 986333 = 986512
521 + 985991 = 986512

Showing the first eight; more decompositions exist.
