Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638226, here are decompositions:

7 + 8638219 = 8638226
13 + 8638213 = 8638226
19 + 8638207 = 8638226
43 + 8638183 = 8638226
109 + 8638117 = 8638226
193 + 8638033 = 8638226
283 + 8637943 = 8638226
379 + 8637847 = 8638226

Showing the first eight; more decompositions exist.
