Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71146, here are decompositions:

3 + 71143 = 71146
17 + 71129 = 71146
107 + 71039 = 71146
149 + 70997 = 71146
167 + 70979 = 71146
197 + 70949 = 71146
227 + 70919 = 71146
233 + 70913 = 71146

Showing the first eight; more decompositions exist.
