Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161012, here are decompositions:

3 + 161009 = 161012
31 + 160981 = 161012
43 + 160969 = 161012
79 + 160933 = 161012
109 + 160903 = 161012
151 + 160861 = 161012
199 + 160813 = 161012
223 + 160789 = 161012

Showing the first eight; more decompositions exist.
