Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620384, here are decompositions:

23 + 8620361 = 8620384
107 + 8620277 = 8620384
167 + 8620217 = 8620384
173 + 8620211 = 8620384
197 + 8620187 = 8620384
233 + 8620151 = 8620384
251 + 8620133 = 8620384
263 + 8620121 = 8620384

Showing the first eight; more decompositions exist.
