Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643504, here are decompositions:

17 + 8643487 = 8643504
47 + 8643457 = 8643504
61 + 8643443 = 8643504
71 + 8643433 = 8643504
137 + 8643367 = 8643504
167 + 8643337 = 8643504
197 + 8643307 = 8643504
223 + 8643281 = 8643504

Showing the first eight; more decompositions exist.
