Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647908, here are decompositions:

11 + 8647897 = 8647908
19 + 8647889 = 8647908
29 + 8647879 = 8647908
89 + 8647819 = 8647908
107 + 8647801 = 8647908
149 + 8647759 = 8647908
197 + 8647711 = 8647908
211 + 8647697 = 8647908

Showing the first eight; more decompositions exist.
