Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185188, here are decompositions:

5 + 185183 = 185188
11 + 185177 = 185188
89 + 185099 = 185188
131 + 185057 = 185188
137 + 185051 = 185188
167 + 185021 = 185188
191 + 184997 = 185188
239 + 184949 = 185188

Showing the first eight; more decompositions exist.
