Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71086, here are decompositions:

5 + 71081 = 71086
17 + 71069 = 71086
47 + 71039 = 71086
89 + 70997 = 71086
107 + 70979 = 71086
137 + 70949 = 71086
149 + 70937 = 71086
167 + 70919 = 71086

Showing the first eight; more decompositions exist.
