Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660384, here are decompositions:

3 + 8660381 = 8660384
97 + 8660287 = 8660384
151 + 8660233 = 8660384
157 + 8660227 = 8660384
163 + 8660221 = 8660384
181 + 8660203 = 8660384
223 + 8660161 = 8660384
277 + 8660107 = 8660384

Showing the first eight; more decompositions exist.
