Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457332, here are decompositions:

3 + 31457329 = 31457332
29 + 31457303 = 31457332
131 + 31457201 = 31457332
173 + 31457159 = 31457332
233 + 31457099 = 31457332
239 + 31457093 = 31457332
251 + 31457081 = 31457332
281 + 31457051 = 31457332

Showing the first eight; more decompositions exist.
