Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638324, here are decompositions:

5 + 8638319 = 8638324
41 + 8638283 = 8638324
47 + 8638277 = 8638324
83 + 8638241 = 8638324
137 + 8638187 = 8638324
173 + 8638151 = 8638324
257 + 8638067 = 8638324
263 + 8638061 = 8638324

Showing the first eight; more decompositions exist.
