Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641074, here are decompositions:

11 + 8641063 = 8641074
67 + 8641007 = 8641074
97 + 8640977 = 8641074
107 + 8640967 = 8641074
163 + 8640911 = 8641074
191 + 8640883 = 8641074
251 + 8640823 = 8641074
257 + 8640817 = 8641074

Showing the first eight; more decompositions exist.
