Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169340, here are decompositions:

13 + 169327 = 169340
19 + 169321 = 169340
97 + 169243 = 169340
163 + 169177 = 169340
181 + 169159 = 169340
211 + 169129 = 169340
229 + 169111 = 169340
271 + 169069 = 169340

Showing the first eight; more decompositions exist.
