Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166194, here are decompositions:

5 + 166189 = 166194
11 + 166183 = 166194
37 + 166157 = 166194
43 + 166151 = 166194
47 + 166147 = 166194
113 + 166081 = 166194
131 + 166063 = 166194
151 + 166043 = 166194

Showing the first eight; more decompositions exist.
