Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456314, here are decompositions:

23 + 31456291 = 31456314
37 + 31456277 = 31456314
67 + 31456247 = 31456314
73 + 31456241 = 31456314
151 + 31456163 = 31456314
191 + 31456123 = 31456314
193 + 31456121 = 31456314
293 + 31456021 = 31456314

Showing the first eight; more decompositions exist.
