Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171670, here are decompositions:

11 + 171659 = 171670
17 + 171653 = 171670
29 + 171641 = 171670
41 + 171629 = 171670
53 + 171617 = 171670
131 + 171539 = 171670
179 + 171491 = 171670
197 + 171473 = 171670

Showing the first eight; more decompositions exist.
