Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627198, here are decompositions:

7 + 8627191 = 8627198
31 + 8627167 = 8627198
37 + 8627161 = 8627198
79 + 8627119 = 8627198
199 + 8626999 = 8627198
271 + 8626927 = 8627198
337 + 8626861 = 8627198
367 + 8626831 = 8627198

Showing the first eight; more decompositions exist.
