Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563218, here are decompositions:

101 + 563117 = 563218
137 + 563081 = 563218
167 + 563051 = 563218
179 + 563039 = 563218
197 + 563021 = 563218
239 + 562979 = 563218
251 + 562967 = 563218
269 + 562949 = 563218

Showing the first eight; more decompositions exist.
