Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617986, here are decompositions:

37 + 8617949 = 8617986
43 + 8617943 = 8617986
53 + 8617933 = 8617986
59 + 8617927 = 8617986
109 + 8617877 = 8617986
149 + 8617837 = 8617986
163 + 8617823 = 8617986
199 + 8617787 = 8617986

Showing the first eight; more decompositions exist.
