Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471364, here are decompositions:

3 + 31471361 = 31471364
7 + 31471357 = 31471364
151 + 31471213 = 31471364
157 + 31471207 = 31471364
193 + 31471171 = 31471364
241 + 31471123 = 31471364
271 + 31471093 = 31471364
313 + 31471051 = 31471364

Showing the first eight; more decompositions exist.
