Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638068, here are decompositions:

7 + 8638061 = 8638068
17 + 8638051 = 8638068
29 + 8638039 = 8638068
139 + 8637929 = 8638068
199 + 8637869 = 8638068
239 + 8637829 = 8638068
277 + 8637791 = 8638068
281 + 8637787 = 8638068

Showing the first eight; more decompositions exist.
