Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639412, here are decompositions:

11 + 8639401 = 8639412
31 + 8639381 = 8639412
113 + 8639299 = 8639412
139 + 8639273 = 8639412
149 + 8639263 = 8639412
151 + 8639261 = 8639412
163 + 8639249 = 8639412
193 + 8639219 = 8639412

Showing the first eight; more decompositions exist.
