Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623224, here are decompositions:

11 + 8623213 = 8623224
31 + 8623193 = 8623224
83 + 8623141 = 8623224
101 + 8623123 = 8623224
151 + 8623073 = 8623224
157 + 8623067 = 8623224
163 + 8623061 = 8623224
173 + 8623051 = 8623224

Showing the first eight; more decompositions exist.
