Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164186, here are decompositions:

3 + 164183 = 164186
13 + 164173 = 164186
37 + 164149 = 164186
73 + 164113 = 164186
97 + 164089 = 164186
163 + 164023 = 164186
193 + 163993 = 164186
199 + 163987 = 164186

Showing the first eight; more decompositions exist.
