Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644224, here are decompositions:

11 + 8644213 = 8644224
37 + 8644187 = 8644224
53 + 8644171 = 8644224
67 + 8644157 = 8644224
101 + 8644123 = 8644224
163 + 8644061 = 8644224
167 + 8644057 = 8644224
227 + 8643997 = 8644224

Showing the first eight; more decompositions exist.
