Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669784, here are decompositions:

7 + 8669777 = 8669784
17 + 8669767 = 8669784
83 + 8669701 = 8669784
113 + 8669671 = 8669784
127 + 8669657 = 8669784
157 + 8669627 = 8669784
163 + 8669621 = 8669784
173 + 8669611 = 8669784

Showing the first eight; more decompositions exist.
