Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168198, here are decompositions:

5 + 168193 = 168198
47 + 168151 = 168198
71 + 168127 = 168198
89 + 168109 = 168198
109 + 168089 = 168198
127 + 168071 = 168198
131 + 168067 = 168198
211 + 167987 = 168198

Showing the first eight; more decompositions exist.
