Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171650, here are decompositions:

13 + 171637 = 171650
67 + 171583 = 171650
79 + 171571 = 171650
97 + 171553 = 171650
109 + 171541 = 171650
181 + 171469 = 171650
211 + 171439 = 171650
223 + 171427 = 171650

Showing the first eight; more decompositions exist.
