Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571476, here are decompositions:

23 + 31571453 = 31571476
29 + 31571447 = 31571476
149 + 31571327 = 31571476
173 + 31571303 = 31571476
257 + 31571219 = 31571476
263 + 31571213 = 31571476
269 + 31571207 = 31571476
467 + 31571009 = 31571476

Showing the first eight; more decompositions exist.
