Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475252, here are decompositions:

43 + 31475209 = 31475252
163 + 31475089 = 31475252
181 + 31475071 = 31475252
199 + 31475053 = 31475252
223 + 31475029 = 31475252
271 + 31474981 = 31475252
283 + 31474969 = 31475252
379 + 31474873 = 31475252

Showing the first eight; more decompositions exist.
