Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641116, here are decompositions:

19 + 8641097 = 8641116
23 + 8641093 = 8641116
37 + 8641079 = 8641116
53 + 8641063 = 8641116
109 + 8641007 = 8641116
139 + 8640977 = 8641116
149 + 8640967 = 8641116
167 + 8640949 = 8641116

Showing the first eight; more decompositions exist.
