Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169170, here are decompositions:

11 + 169159 = 169170
19 + 169151 = 169170
41 + 169129 = 169170
59 + 169111 = 169170
73 + 169097 = 169170
101 + 169069 = 169170
103 + 169067 = 169170
107 + 169063 = 169170

Showing the first eight; more decompositions exist.
