Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669108, here are decompositions:

37 + 8669071 = 8669108
67 + 8669041 = 8669108
157 + 8668951 = 8669108
211 + 8668897 = 8669108
271 + 8668837 = 8669108
277 + 8668831 = 8669108
307 + 8668801 = 8669108
367 + 8668741 = 8669108

Showing the first eight; more decompositions exist.
