Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622198, here are decompositions:

7 + 8622191 = 8622198
61 + 8622137 = 8622198
71 + 8622127 = 8622198
127 + 8622071 = 8622198
157 + 8622041 = 8622198
181 + 8622017 = 8622198
191 + 8622007 = 8622198
197 + 8622001 = 8622198

Showing the first eight; more decompositions exist.
