Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171966, here are decompositions:

19 + 171947 = 171966
29 + 171937 = 171966
37 + 171929 = 171966
43 + 171923 = 171966
89 + 171877 = 171966
97 + 171869 = 171966
103 + 171863 = 171966
139 + 171827 = 171966

Showing the first eight; more decompositions exist.
