Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668356, here are decompositions:

7 + 8668349 = 8668356
83 + 8668273 = 8668356
89 + 8668267 = 8668356
149 + 8668207 = 8668356
163 + 8668193 = 8668356
199 + 8668157 = 8668356
223 + 8668133 = 8668356
283 + 8668073 = 8668356

Showing the first eight; more decompositions exist.
