Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178086, here are decompositions:

17 + 178069 = 178086
19 + 178067 = 178086
47 + 178039 = 178086
107 + 177979 = 178086
137 + 177949 = 178086
157 + 177929 = 178086
173 + 177913 = 178086
179 + 177907 = 178086

Showing the first eight; more decompositions exist.
