Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597160, here are decompositions:

31 + 31597129 = 31597160
61 + 31597099 = 31597160
79 + 31597081 = 31597160
109 + 31597051 = 31597160
157 + 31597003 = 31597160
163 + 31596997 = 31597160
211 + 31596949 = 31597160
271 + 31596889 = 31597160

Showing the first eight; more decompositions exist.
