Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669136, here are decompositions:

13 + 8669123 = 8669136
19 + 8669117 = 8669136
23 + 8669113 = 8669136
29 + 8669107 = 8669136
53 + 8669083 = 8669136
109 + 8669027 = 8669136
163 + 8668973 = 8669136
239 + 8668897 = 8669136

Showing the first eight; more decompositions exist.
