Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638066, here are decompositions:

5 + 8638061 = 8638066
23 + 8638043 = 8638066
113 + 8637953 = 8638066
137 + 8637929 = 8638066
197 + 8637869 = 8638066
317 + 8637749 = 8638066
449 + 8637617 = 8638066
557 + 8637509 = 8638066

Showing the first eight; more decompositions exist.
