Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647224, here are decompositions:

31 + 8647193 = 8647224
41 + 8647183 = 8647224
43 + 8647181 = 8647224
67 + 8647157 = 8647224
97 + 8647127 = 8647224
101 + 8647123 = 8647224
163 + 8647061 = 8647224
181 + 8647043 = 8647224

Showing the first eight; more decompositions exist.
