Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571466, here are decompositions:

13 + 31571453 = 31571466
19 + 31571447 = 31571466
29 + 31571437 = 31571466
53 + 31571413 = 31571466
67 + 31571399 = 31571466
83 + 31571383 = 31571466
139 + 31571327 = 31571466
163 + 31571303 = 31571466

Showing the first eight; more decompositions exist.
