Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571594, here are decompositions:

3 + 31571591 = 31571594
37 + 31571557 = 31571594
97 + 31571497 = 31571594
127 + 31571467 = 31571594
157 + 31571437 = 31571594
181 + 31571413 = 31571594
211 + 31571383 = 31571594
337 + 31571257 = 31571594

Showing the first eight; more decompositions exist.
