Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651966, here are decompositions:

7 + 8651959 = 8651966
13 + 8651953 = 8651966
73 + 8651893 = 8651966
97 + 8651869 = 8651966
109 + 8651857 = 8651966
163 + 8651803 = 8651966
229 + 8651737 = 8651966
277 + 8651689 = 8651966

Showing the first eight; more decompositions exist.
