Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160280, here are decompositions:

37 + 160243 = 160280
73 + 160207 = 160280
79 + 160201 = 160280
97 + 160183 = 160280
139 + 160141 = 160280
163 + 160117 = 160280
193 + 160087 = 160280
199 + 160081 = 160280

Showing the first eight; more decompositions exist.
