Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571482, here are decompositions:

29 + 31571453 = 31571482
83 + 31571399 = 31571482
101 + 31571381 = 31571482
149 + 31571333 = 31571482
179 + 31571303 = 31571482
263 + 31571219 = 31571482
269 + 31571213 = 31571482
281 + 31571201 = 31571482

Showing the first eight; more decompositions exist.
