Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643066, here are decompositions:

7 + 8643059 = 8643066
13 + 8643053 = 8643066
43 + 8643023 = 8643066
53 + 8643013 = 8643066
127 + 8642939 = 8643066
139 + 8642927 = 8643066
163 + 8642903 = 8643066
227 + 8642839 = 8643066

Showing the first eight; more decompositions exist.
