Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457466, here are decompositions:

13 + 31457453 = 31457466
17 + 31457449 = 31457466
83 + 31457383 = 31457466
137 + 31457329 = 31457466
163 + 31457303 = 31457466
179 + 31457287 = 31457466
197 + 31457269 = 31457466
199 + 31457267 = 31457466

Showing the first eight; more decompositions exist.
