Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639224, here are decompositions:

5 + 8639219 = 8639224
17 + 8639207 = 8639224
47 + 8639177 = 8639224
53 + 8639171 = 8639224
71 + 8639153 = 8639224
101 + 8639123 = 8639224
173 + 8639051 = 8639224
197 + 8639027 = 8639224

Showing the first eight; more decompositions exist.
