Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171198, here are decompositions:

19 + 171179 = 171198
29 + 171169 = 171198
31 + 171167 = 171198
37 + 171161 = 171198
67 + 171131 = 171198
107 + 171091 = 171198
149 + 171049 = 171198
151 + 171047 = 171198

Showing the first eight; more decompositions exist.
