Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169956, here are decompositions:

5 + 169951 = 169956
13 + 169943 = 169956
19 + 169937 = 169956
23 + 169933 = 169956
37 + 169919 = 169956
43 + 169913 = 169956
47 + 169909 = 169956
67 + 169889 = 169956

Showing the first eight; more decompositions exist.
