Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571652, here are decompositions:

5 + 31571647 = 31571652
31 + 31571621 = 31571652
41 + 31571611 = 31571652
61 + 31571591 = 31571652
83 + 31571569 = 31571652
199 + 31571453 = 31571652
239 + 31571413 = 31571652
263 + 31571389 = 31571652

Showing the first eight; more decompositions exist.
