Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457274, here are decompositions:

5 + 31457269 = 31457274
7 + 31457267 = 31457274
47 + 31457227 = 31457274
71 + 31457203 = 31457274
73 + 31457201 = 31457274
103 + 31457171 = 31457274
181 + 31457093 = 31457274
193 + 31457081 = 31457274

Showing the first eight; more decompositions exist.
