Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668224, here are decompositions:

17 + 8668207 = 8668224
23 + 8668201 = 8668224
31 + 8668193 = 8668224
67 + 8668157 = 8668224
73 + 8668151 = 8668224
83 + 8668141 = 8668224
113 + 8668111 = 8668224
151 + 8668073 = 8668224

Showing the first eight; more decompositions exist.
