Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457492, here are decompositions:

13 + 31457479 = 31457492
43 + 31457449 = 31457492
109 + 31457383 = 31457492
151 + 31457341 = 31457492
163 + 31457329 = 31457492
181 + 31457311 = 31457492
223 + 31457269 = 31457492
373 + 31457119 = 31457492

Showing the first eight; more decompositions exist.
