Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171660, here are decompositions:

7 + 171653 = 171660
19 + 171641 = 171660
23 + 171637 = 171660
31 + 171629 = 171660
43 + 171617 = 171660
89 + 171571 = 171660
101 + 171559 = 171660
107 + 171553 = 171660

Showing the first eight; more decompositions exist.
