Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636224, here are decompositions:

5 + 8636219 = 8636224
83 + 8636141 = 8636224
101 + 8636123 = 8636224
131 + 8636093 = 8636224
137 + 8636087 = 8636224
167 + 8636057 = 8636224
257 + 8635967 = 8636224
557 + 8635667 = 8636224

Showing the first eight; more decompositions exist.
