Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457604, here are decompositions:

47 + 31457557 = 31457604
151 + 31457453 = 31457604
193 + 31457411 = 31457604
257 + 31457347 = 31457604
263 + 31457341 = 31457604
293 + 31457311 = 31457604
307 + 31457297 = 31457604
317 + 31457287 = 31457604

Showing the first eight; more decompositions exist.
