Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601986, here are decompositions:

7 + 8601979 = 8601986
79 + 8601907 = 8601986
103 + 8601883 = 8601986
109 + 8601877 = 8601986
163 + 8601823 = 8601986
487 + 8601499 = 8601986
643 + 8601343 = 8601986
709 + 8601277 = 8601986

Showing the first eight; more decompositions exist.
