Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624224, here are decompositions:

3 + 8624221 = 8624224
23 + 8624201 = 8624224
41 + 8624183 = 8624224
47 + 8624177 = 8624224
71 + 8624153 = 8624224
83 + 8624141 = 8624224
113 + 8624111 = 8624224
173 + 8624051 = 8624224

Showing the first eight; more decompositions exist.
