Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697966, here are decompositions:

19 + 8697947 = 8697966
23 + 8697943 = 8697966
29 + 8697937 = 8697966
47 + 8697919 = 8697966
97 + 8697869 = 8697966
107 + 8697859 = 8697966
157 + 8697809 = 8697966
163 + 8697803 = 8697966

Showing the first eight; more decompositions exist.
