Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3160, here are decompositions:

23 + 3137 = 3160
41 + 3119 = 3160
71 + 3089 = 3160
137 + 3023 = 3160
149 + 3011 = 3160
191 + 2969 = 3160
197 + 2963 = 3160
233 + 2927 = 3160

Showing the first eight; more decompositions exist.
