Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636966, here are decompositions:

7 + 8636959 = 8636966
43 + 8636923 = 8636966
67 + 8636899 = 8636966
73 + 8636893 = 8636966
97 + 8636869 = 8636966
109 + 8636857 = 8636966
127 + 8636839 = 8636966
229 + 8636737 = 8636966

Showing the first eight; more decompositions exist.
