Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186198, here are decompositions:

7 + 186191 = 186198
11 + 186187 = 186198
37 + 186161 = 186198
41 + 186157 = 186198
79 + 186119 = 186198
101 + 186097 = 186198
127 + 186071 = 186198
149 + 186049 = 186198

Showing the first eight; more decompositions exist.
