Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172086, here are decompositions:

7 + 172079 = 172086
17 + 172069 = 172086
37 + 172049 = 172086
59 + 172027 = 172086
139 + 171947 = 172086
149 + 171937 = 172086
157 + 171929 = 172086
163 + 171923 = 172086

Showing the first eight; more decompositions exist.
