Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71164, here are decompositions:

3 + 71161 = 71164
11 + 71153 = 71164
17 + 71147 = 71164
83 + 71081 = 71164
167 + 70997 = 71164
173 + 70991 = 71164
227 + 70937 = 71164
251 + 70913 = 71164

Showing the first eight; more decompositions exist.
