Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649224, here are decompositions:

13 + 8649211 = 8649224
37 + 8649187 = 8649224
163 + 8649061 = 8649224
223 + 8649001 = 8649224
271 + 8648953 = 8649224
433 + 8648791 = 8649224
487 + 8648737 = 8649224
523 + 8648701 = 8649224

Showing the first eight; more decompositions exist.
