Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160220, here are decompositions:

3 + 160217 = 160220
13 + 160207 = 160220
19 + 160201 = 160220
37 + 160183 = 160220
61 + 160159 = 160220
79 + 160141 = 160220
103 + 160117 = 160220
127 + 160093 = 160220

Showing the first eight; more decompositions exist.
