Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162166, here are decompositions:

23 + 162143 = 162166
47 + 162119 = 162166
107 + 162059 = 162166
113 + 162053 = 162166
149 + 162017 = 162166
167 + 161999 = 162166
197 + 161969 = 162166
293 + 161873 = 162166

Showing the first eight; more decompositions exist.
