Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672384, here are decompositions:

3 + 8672381 = 8672384
31 + 8672353 = 8672384
37 + 8672347 = 8672384
181 + 8672203 = 8672384
223 + 8672161 = 8672384
283 + 8672101 = 8672384
337 + 8672047 = 8672384
397 + 8671987 = 8672384

Showing the first eight; more decompositions exist.
