Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647018, here are decompositions:

11 + 8647007 = 8647018
47 + 8646971 = 8647018
71 + 8646947 = 8647018
89 + 8646929 = 8647018
167 + 8646851 = 8647018
197 + 8646821 = 8647018
239 + 8646779 = 8647018
311 + 8646707 = 8647018

Showing the first eight; more decompositions exist.
