Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621958, here are decompositions:

11 + 8621947 = 8621958
19 + 8621939 = 8621958
31 + 8621927 = 8621958
47 + 8621911 = 8621958
61 + 8621897 = 8621958
89 + 8621869 = 8621958
97 + 8621861 = 8621958
101 + 8621857 = 8621958

Showing the first eight; more decompositions exist.
