Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571176, here are decompositions:

29 + 31571147 = 31571176
113 + 31571063 = 31571176
137 + 31571039 = 31571176
167 + 31571009 = 31571176
179 + 31570997 = 31571176
227 + 31570949 = 31571176
257 + 31570919 = 31571176
269 + 31570907 = 31571176

Showing the first eight; more decompositions exist.
