Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651922, here are decompositions:

5 + 8651917 = 8651922
29 + 8651893 = 8651922
31 + 8651891 = 8651922
53 + 8651869 = 8651922
131 + 8651791 = 8651922
151 + 8651771 = 8651922
199 + 8651723 = 8651922
211 + 8651711 = 8651922

Showing the first eight; more decompositions exist.
