Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457496, here are decompositions:

17 + 31457479 = 31457496
43 + 31457453 = 31457496
47 + 31457449 = 31457496
113 + 31457383 = 31457496
149 + 31457347 = 31457496
167 + 31457329 = 31457496
193 + 31457303 = 31457496
199 + 31457297 = 31457496

Showing the first eight; more decompositions exist.
