Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571596, here are decompositions:

5 + 31571591 = 31571596
149 + 31571447 = 31571596
197 + 31571399 = 31571596
263 + 31571333 = 31571596
269 + 31571327 = 31571596
293 + 31571303 = 31571596
383 + 31571213 = 31571596
389 + 31571207 = 31571596

Showing the first eight; more decompositions exist.
