Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572022, here are decompositions:

5 + 31572017 = 31572022
29 + 31571993 = 31572022
59 + 31571963 = 31572022
173 + 31571849 = 31572022
401 + 31571621 = 31572022
431 + 31571591 = 31572022
569 + 31571453 = 31572022
641 + 31571381 = 31572022

Showing the first eight; more decompositions exist.
