Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111198, here are decompositions:

7 + 111191 = 111198
11 + 111187 = 111198
71 + 111127 = 111198
79 + 111119 = 111198
89 + 111109 = 111198
107 + 111091 = 111198
149 + 111049 = 111198
167 + 111031 = 111198

Showing the first eight; more decompositions exist.
