Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637966, here are decompositions:

13 + 8637953 = 8637966
23 + 8637943 = 8637966
37 + 8637929 = 8637966
97 + 8637869 = 8637966
137 + 8637829 = 8637966
179 + 8637787 = 8637966
269 + 8637697 = 8637966
347 + 8637619 = 8637966

Showing the first eight; more decompositions exist.
