Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171950, here are decompositions:

3 + 171947 = 171950
13 + 171937 = 171950
61 + 171889 = 171950
73 + 171877 = 171950
127 + 171823 = 171950
139 + 171811 = 171950
151 + 171799 = 171950
157 + 171793 = 171950

Showing the first eight; more decompositions exist.
