Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161074, here are decompositions:

3 + 161071 = 161074
41 + 161033 = 161074
107 + 160967 = 161074
167 + 160907 = 161074
191 + 160883 = 161074
197 + 160877 = 161074
233 + 160841 = 161074
257 + 160817 = 161074

Showing the first eight; more decompositions exist.
