Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629938, here are decompositions:

11 + 8629927 = 8629938
29 + 8629909 = 8629938
47 + 8629891 = 8629938
71 + 8629867 = 8629938
167 + 8629771 = 8629938
199 + 8629739 = 8629938
227 + 8629711 = 8629938
257 + 8629681 = 8629938

Showing the first eight; more decompositions exist.
