Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471314, here are decompositions:

97 + 31471217 = 31471314
101 + 31471213 = 31471314
107 + 31471207 = 31471314
167 + 31471147 = 31471314
191 + 31471123 = 31471314
223 + 31471091 = 31471314
263 + 31471051 = 31471314
271 + 31471043 = 31471314

Showing the first eight; more decompositions exist.
