Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677986, here are decompositions:

7 + 8677979 = 8677986
19 + 8677967 = 8677986
103 + 8677883 = 8677986
139 + 8677847 = 8677986
157 + 8677829 = 8677986
223 + 8677763 = 8677986
227 + 8677759 = 8677986
263 + 8677723 = 8677986

Showing the first eight; more decompositions exist.
