Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171178, here are decompositions:

11 + 171167 = 171178
17 + 171161 = 171178
47 + 171131 = 171178
101 + 171077 = 171178
131 + 171047 = 171178
149 + 171029 = 171178
251 + 170927 = 171178
257 + 170921 = 171178

Showing the first eight; more decompositions exist.
