Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738266, here are decompositions:

3 + 8738263 = 8738266
137 + 8738129 = 8738266
179 + 8738087 = 8738266
233 + 8738033 = 8738266
503 + 8737763 = 8738266
557 + 8737709 = 8738266
569 + 8737697 = 8738266
599 + 8737667 = 8738266

Showing the first eight; more decompositions exist.
