Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613198, here are decompositions:

17 + 8613181 = 8613198
37 + 8613161 = 8613198
71 + 8613127 = 8613198
107 + 8613091 = 8613198
109 + 8613089 = 8613198
151 + 8613047 = 8613198
157 + 8613041 = 8613198
179 + 8613019 = 8613198

Showing the first eight; more decompositions exist.
