Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162160, here are decompositions:

17 + 162143 = 162160
41 + 162119 = 162160
101 + 162059 = 162160
107 + 162053 = 162160
149 + 162011 = 162160
191 + 161969 = 162160
239 + 161921 = 162160
281 + 161879 = 162160

Showing the first eight; more decompositions exist.
