Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643036, here are decompositions:

13 + 8643023 = 8643036
23 + 8643013 = 8643036
47 + 8642989 = 8643036
89 + 8642947 = 8643036
97 + 8642939 = 8643036
109 + 8642927 = 8643036
139 + 8642897 = 8643036
173 + 8642863 = 8643036

Showing the first eight; more decompositions exist.
