Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641108, here are decompositions:

11 + 8641097 = 8641108
29 + 8641079 = 8641108
101 + 8641007 = 8641108
131 + 8640977 = 8641108
197 + 8640911 = 8641108
347 + 8640761 = 8641108
389 + 8640719 = 8641108
401 + 8640707 = 8641108

Showing the first eight; more decompositions exist.
