Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628224, here are decompositions:

37 + 8628187 = 8628224
43 + 8628181 = 8628224
67 + 8628157 = 8628224
103 + 8628121 = 8628224
127 + 8628097 = 8628224
193 + 8628031 = 8628224
271 + 8627953 = 8628224
277 + 8627947 = 8628224

Showing the first eight; more decompositions exist.
