Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669178, here are decompositions:

19 + 8669159 = 8669178
61 + 8669117 = 8669178
71 + 8669107 = 8669178
107 + 8669071 = 8669178
137 + 8669041 = 8669178
151 + 8669027 = 8669178
211 + 8668967 = 8669178
227 + 8668951 = 8669178

Showing the first eight; more decompositions exist.
