Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643324, here are decompositions:

7 + 8643317 = 8643324
17 + 8643307 = 8643324
37 + 8643287 = 8643324
43 + 8643281 = 8643324
101 + 8643223 = 8643324
113 + 8643211 = 8643324
127 + 8643197 = 8643324
181 + 8643143 = 8643324

Showing the first eight; more decompositions exist.
