Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571364, here are decompositions:

17 + 31571347 = 31571364
31 + 31571333 = 31571364
37 + 31571327 = 31571364
61 + 31571303 = 31571364
107 + 31571257 = 31571364
151 + 31571213 = 31571364
157 + 31571207 = 31571364
163 + 31571201 = 31571364

Showing the first eight; more decompositions exist.
