Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639416, here are decompositions:

3 + 8639413 = 8639416
53 + 8639363 = 8639416
167 + 8639249 = 8639416
197 + 8639219 = 8639416
239 + 8639177 = 8639416
263 + 8639153 = 8639416
293 + 8639123 = 8639416
353 + 8639063 = 8639416

Showing the first eight; more decompositions exist.
