Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643026, here are decompositions:

3 + 8643023 = 8643026
13 + 8643013 = 8643026
37 + 8642989 = 8643026
79 + 8642947 = 8643026
163 + 8642863 = 8643026
577 + 8642449 = 8643026
643 + 8642383 = 8643026
829 + 8642197 = 8643026

Showing the first eight; more decompositions exist.
