Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171636, here are decompositions:

7 + 171629 = 171636
19 + 171617 = 171636
53 + 171583 = 171636
83 + 171553 = 171636
97 + 171539 = 171636
107 + 171529 = 171636
163 + 171473 = 171636
167 + 171469 = 171636

Showing the first eight; more decompositions exist.
