Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171974, here are decompositions:

37 + 171937 = 171974
97 + 171877 = 171974
151 + 171823 = 171974
163 + 171811 = 171974
181 + 171793 = 171974
211 + 171763 = 171974
241 + 171733 = 171974
277 + 171697 = 171974

Showing the first eight; more decompositions exist.
