Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171188, here are decompositions:

19 + 171169 = 171188
97 + 171091 = 171188
109 + 171079 = 171188
139 + 171049 = 171188
181 + 171007 = 171188
307 + 170881 = 171188
331 + 170857 = 171188
337 + 170851 = 171188

Showing the first eight; more decompositions exist.
