Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162198, here are decompositions:

79 + 162119 = 162198
89 + 162109 = 162198
107 + 162091 = 162198
139 + 162059 = 162198
181 + 162017 = 162198
191 + 162007 = 162198
199 + 161999 = 162198
227 + 161971 = 162198

Showing the first eight; more decompositions exist.
