Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169160, here are decompositions:

31 + 169129 = 169160
67 + 169093 = 169160
97 + 169063 = 169160
151 + 169009 = 169160
157 + 169003 = 169160
223 + 168937 = 169160
379 + 168781 = 169160
463 + 168697 = 169160

Showing the first eight; more decompositions exist.
