Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644066, here are decompositions:

5 + 8644061 = 8644066
17 + 8644049 = 8644066
47 + 8644019 = 8644066
107 + 8643959 = 8644066
113 + 8643953 = 8644066
173 + 8643893 = 8644066
227 + 8643839 = 8644066
269 + 8643797 = 8644066

Showing the first eight; more decompositions exist.
