Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188184, here are decompositions:

5 + 188179 = 188184
13 + 188171 = 188184
37 + 188147 = 188184
41 + 188143 = 188184
47 + 188137 = 188184
163 + 188021 = 188184
167 + 188017 = 188184
173 + 188011 = 188184

Showing the first eight; more decompositions exist.
