Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690966, here are decompositions:

3 + 8690963 = 8690966
7 + 8690959 = 8690966
13 + 8690953 = 8690966
19 + 8690947 = 8690966
139 + 8690827 = 8690966
199 + 8690767 = 8690966
283 + 8690683 = 8690966
307 + 8690659 = 8690966

Showing the first eight; more decompositions exist.
