Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641384, here are decompositions:

23 + 8641361 = 8641384
53 + 8641331 = 8641384
83 + 8641301 = 8641384
137 + 8641247 = 8641384
173 + 8641211 = 8641384
197 + 8641187 = 8641384
251 + 8641133 = 8641384
617 + 8640767 = 8641384

Showing the first eight; more decompositions exist.
