Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647986, here are decompositions:

7 + 8647979 = 8647986
19 + 8647967 = 8647986
23 + 8647963 = 8647986
37 + 8647949 = 8647986
59 + 8647927 = 8647986
73 + 8647913 = 8647986
89 + 8647897 = 8647986
97 + 8647889 = 8647986

Showing the first eight; more decompositions exist.
