Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638214, here are decompositions:

7 + 8638207 = 8638214
31 + 8638183 = 8638214
97 + 8638117 = 8638214
163 + 8638051 = 8638214
181 + 8638033 = 8638214
223 + 8637991 = 8638214
241 + 8637973 = 8638214
271 + 8637943 = 8638214

Showing the first eight; more decompositions exist.
