Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638384, here are decompositions:

3 + 8638381 = 8638384
5 + 8638379 = 8638384
11 + 8638373 = 8638384
47 + 8638337 = 8638384
101 + 8638283 = 8638384
107 + 8638277 = 8638384
137 + 8638247 = 8638384
197 + 8638187 = 8638384

Showing the first eight; more decompositions exist.
