Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571552, here are decompositions:

139 + 31571413 = 31571552
163 + 31571389 = 31571552
409 + 31571143 = 31571552
613 + 31570939 = 31571552
643 + 31570909 = 31571552
709 + 31570843 = 31571552
1033 + 31570519 = 31571552
1051 + 31570501 = 31571552

Showing the first eight; more decompositions exist.
