Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171306, here are decompositions:

7 + 171299 = 171306
13 + 171293 = 171306
43 + 171263 = 171306
53 + 171253 = 171306
73 + 171233 = 171306
103 + 171203 = 171306
127 + 171179 = 171306
137 + 171169 = 171306

Showing the first eight; more decompositions exist.
