Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643016, here are decompositions:

3 + 8643013 = 8643016
89 + 8642927 = 8643016
113 + 8642903 = 8643016
167 + 8642849 = 8643016
197 + 8642819 = 8643016
269 + 8642747 = 8643016
293 + 8642723 = 8643016
383 + 8642633 = 8643016

Showing the first eight; more decompositions exist.
