Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629878, here are decompositions:

11 + 8629867 = 8629878
31 + 8629847 = 8629878
107 + 8629771 = 8629878
139 + 8629739 = 8629878
167 + 8629711 = 8629878
197 + 8629681 = 8629878
199 + 8629679 = 8629878
227 + 8629651 = 8629878

Showing the first eight; more decompositions exist.
