Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641104, here are decompositions:

7 + 8641097 = 8641104
11 + 8641093 = 8641104
41 + 8641063 = 8641104
97 + 8641007 = 8641104
127 + 8640977 = 8641104
137 + 8640967 = 8641104
193 + 8640911 = 8641104
233 + 8640871 = 8641104

Showing the first eight; more decompositions exist.
