Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457454, here are decompositions:

5 + 31457449 = 31457454
43 + 31457411 = 31457454
71 + 31457383 = 31457454
107 + 31457347 = 31457454
113 + 31457341 = 31457454
151 + 31457303 = 31457454
157 + 31457297 = 31457454
167 + 31457287 = 31457454

Showing the first eight; more decompositions exist.
