Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647108, here are decompositions:

17 + 8647091 = 8647108
47 + 8647061 = 8647108
101 + 8647007 = 8647108
137 + 8646971 = 8647108
179 + 8646929 = 8647108
257 + 8646851 = 8647108
389 + 8646719 = 8647108
401 + 8646707 = 8647108

Showing the first eight; more decompositions exist.
