Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571034, here are decompositions:

13 + 31571021 = 31571034
17 + 31571017 = 31571034
37 + 31570997 = 31571034
41 + 31570993 = 31571034
73 + 31570961 = 31571034
127 + 31570907 = 31571034
167 + 31570867 = 31571034
191 + 31570843 = 31571034

Showing the first eight; more decompositions exist.
