Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457462, here are decompositions:

13 + 31457449 = 31457462
79 + 31457383 = 31457462
151 + 31457311 = 31457462
193 + 31457269 = 31457462
313 + 31457149 = 31457462
571 + 31456891 = 31457462
613 + 31456849 = 31457462
643 + 31456819 = 31457462

Showing the first eight; more decompositions exist.
