Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643064, here are decompositions:

5 + 8643059 = 8643064
11 + 8643053 = 8643064
41 + 8643023 = 8643064
113 + 8642951 = 8643064
137 + 8642927 = 8643064
167 + 8642897 = 8643064
317 + 8642747 = 8643064
431 + 8642633 = 8643064

Showing the first eight; more decompositions exist.
