Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185156, here are decompositions:

3 + 185153 = 185156
7 + 185149 = 185156
19 + 185137 = 185156
67 + 185089 = 185156
79 + 185077 = 185156
157 + 184999 = 185156
163 + 184993 = 185156
199 + 184957 = 185156

Showing the first eight; more decompositions exist.
