Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643384, here are decompositions:

17 + 8643367 = 8643384
41 + 8643343 = 8643384
47 + 8643337 = 8643384
67 + 8643317 = 8643384
97 + 8643287 = 8643384
103 + 8643281 = 8643384
173 + 8643211 = 8643384
241 + 8643143 = 8643384

Showing the first eight; more decompositions exist.
