Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638268, here are decompositions:

31 + 8638237 = 8638268
61 + 8638207 = 8638268
151 + 8638117 = 8638268
229 + 8638039 = 8638268
277 + 8637991 = 8638268
421 + 8637847 = 8638268
439 + 8637829 = 8638268
571 + 8637697 = 8638268

Showing the first eight; more decompositions exist.
