Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171718, here are decompositions:

5 + 171713 = 171718
11 + 171707 = 171718
47 + 171671 = 171718
59 + 171659 = 171718
89 + 171629 = 171718
101 + 171617 = 171718
179 + 171539 = 171718
227 + 171491 = 171718

Showing the first eight; more decompositions exist.
