Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171656, here are decompositions:

3 + 171653 = 171656
19 + 171637 = 171656
73 + 171583 = 171656
97 + 171559 = 171656
103 + 171553 = 171656
127 + 171529 = 171656
139 + 171517 = 171656
229 + 171427 = 171656

Showing the first eight; more decompositions exist.
