Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669778, here are decompositions:

11 + 8669767 = 8669778
107 + 8669671 = 8669778
109 + 8669669 = 8669778
127 + 8669651 = 8669778
149 + 8669629 = 8669778
151 + 8669627 = 8669778
157 + 8669621 = 8669778
167 + 8669611 = 8669778

Showing the first eight; more decompositions exist.
