Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643376, here are decompositions:

17 + 8643359 = 8643376
59 + 8643317 = 8643376
89 + 8643287 = 8643376
167 + 8643209 = 8643376
179 + 8643197 = 8643376
227 + 8643149 = 8643376
233 + 8643143 = 8643376
239 + 8643137 = 8643376

Showing the first eight; more decompositions exist.
