Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643028, here are decompositions:

5 + 8643023 = 8643028
89 + 8642939 = 8643028
101 + 8642927 = 8643028
131 + 8642897 = 8643028
167 + 8642861 = 8643028
179 + 8642849 = 8643028
281 + 8642747 = 8643028
461 + 8642567 = 8643028

Showing the first eight; more decompositions exist.
