Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639386, here are decompositions:

5 + 8639381 = 8639386
23 + 8639363 = 8639386
113 + 8639273 = 8639386
137 + 8639249 = 8639386
167 + 8639219 = 8639386
179 + 8639207 = 8639386
233 + 8639153 = 8639386
263 + 8639123 = 8639386

Showing the first eight; more decompositions exist.
