Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169164, here are decompositions:

5 + 169159 = 169164
13 + 169151 = 169164
53 + 169111 = 169164
67 + 169097 = 169164
71 + 169093 = 169164
97 + 169067 = 169164
101 + 169063 = 169164
157 + 169007 = 169164

Showing the first eight; more decompositions exist.
