Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171340, here are decompositions:

11 + 171329 = 171340
23 + 171317 = 171340
41 + 171299 = 171340
47 + 171293 = 171340
89 + 171251 = 171340
107 + 171233 = 171340
137 + 171203 = 171340
173 + 171167 = 171340

Showing the first eight; more decompositions exist.
