Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457498, here are decompositions:

19 + 31457479 = 31457498
151 + 31457347 = 31457498
157 + 31457341 = 31457498
211 + 31457287 = 31457498
229 + 31457269 = 31457498
271 + 31457227 = 31457498
349 + 31457149 = 31457498
379 + 31457119 = 31457498

Showing the first eight; more decompositions exist.
