Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643084, here are decompositions:

7 + 8643077 = 8643084
31 + 8643053 = 8643084
61 + 8643023 = 8643084
71 + 8643013 = 8643084
137 + 8642947 = 8643084
157 + 8642927 = 8643084
173 + 8642911 = 8643084
181 + 8642903 = 8643084

Showing the first eight; more decompositions exist.
