Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641086, here are decompositions:

7 + 8641079 = 8641086
23 + 8641063 = 8641086
79 + 8641007 = 8641086
109 + 8640977 = 8641086
137 + 8640949 = 8641086
197 + 8640889 = 8641086
199 + 8640887 = 8641086
227 + 8640859 = 8641086

Showing the first eight; more decompositions exist.
