Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457452, here are decompositions:

3 + 31457449 = 31457452
41 + 31457411 = 31457452
149 + 31457303 = 31457452
251 + 31457201 = 31457452
281 + 31457171 = 31457452
293 + 31457159 = 31457452
353 + 31457099 = 31457452
359 + 31457093 = 31457452

Showing the first eight; more decompositions exist.
