Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717966, here are decompositions:

3 + 8717963 = 8717966
7 + 8717959 = 8717966
97 + 8717869 = 8717966
109 + 8717857 = 8717966
157 + 8717809 = 8717966
163 + 8717803 = 8717966
193 + 8717773 = 8717966
199 + 8717767 = 8717966

Showing the first eight; more decompositions exist.
