Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188942, here are decompositions:

3 + 188939 = 188942
31 + 188911 = 188942
73 + 188869 = 188942
79 + 188863 = 188942
109 + 188833 = 188942
151 + 188791 = 188942
163 + 188779 = 188942
223 + 188719 = 188942

Showing the first eight; more decompositions exist.
