Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571662, here are decompositions:

11 + 31571651 = 31571662
41 + 31571621 = 31571662
71 + 31571591 = 31571662
263 + 31571399 = 31571662
281 + 31571381 = 31571662
359 + 31571303 = 31571662
443 + 31571219 = 31571662
449 + 31571213 = 31571662

Showing the first eight; more decompositions exist.
