Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457406, here are decompositions:

23 + 31457383 = 31457406
59 + 31457347 = 31457406
103 + 31457303 = 31457406
109 + 31457297 = 31457406
137 + 31457269 = 31457406
139 + 31457267 = 31457406
179 + 31457227 = 31457406
257 + 31457149 = 31457406

Showing the first eight; more decompositions exist.
