Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638244, here are decompositions:

3 + 8638241 = 8638244
7 + 8638237 = 8638244
31 + 8638213 = 8638244
37 + 8638207 = 8638244
61 + 8638183 = 8638244
127 + 8638117 = 8638244
193 + 8638051 = 8638244
211 + 8638033 = 8638244

Showing the first eight; more decompositions exist.
