Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87160, here are decompositions:

11 + 87149 = 87160
41 + 87119 = 87160
53 + 87107 = 87160
89 + 87071 = 87160
149 + 87011 = 87160
167 + 86993 = 87160
179 + 86981 = 87160
191 + 86969 = 87160

Showing the first eight; more decompositions exist.
