Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171008, here are decompositions:

37 + 170971 = 171008
109 + 170899 = 171008
127 + 170881 = 171008
151 + 170857 = 171008
157 + 170851 = 171008
181 + 170827 = 171008
199 + 170809 = 171008
241 + 170767 = 171008

Showing the first eight; more decompositions exist.
