Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156160, here are decompositions:

3 + 156157 = 156160
29 + 156131 = 156160
41 + 156119 = 156160
71 + 156089 = 156160
89 + 156071 = 156160
101 + 156059 = 156160
149 + 156011 = 156160
239 + 155921 = 156160

Showing the first eight; more decompositions exist.
