Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621922, here are decompositions:

11 + 8621911 = 8621922
53 + 8621869 = 8621922
59 + 8621863 = 8621922
61 + 8621861 = 8621922
79 + 8621843 = 8621922
103 + 8621819 = 8621922
149 + 8621773 = 8621922
173 + 8621749 = 8621922

Showing the first eight; more decompositions exist.
