Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617198, here are decompositions:

11 + 8617187 = 8617198
89 + 8617109 = 8617198
101 + 8617097 = 8617198
197 + 8617001 = 8617198
251 + 8616947 = 8617198
281 + 8616917 = 8617198
311 + 8616887 = 8617198
389 + 8616809 = 8617198

Showing the first eight; more decompositions exist.
