Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188178, here are decompositions:

7 + 188171 = 188178
19 + 188159 = 188178
31 + 188147 = 188178
41 + 188137 = 188178
71 + 188107 = 188178
149 + 188029 = 188178
157 + 188021 = 188178
167 + 188011 = 188178

Showing the first eight; more decompositions exist.
