Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571096, here are decompositions:

13 + 31571083 = 31571096
79 + 31571017 = 31571096
97 + 31570999 = 31571096
103 + 31570993 = 31571096
157 + 31570939 = 31571096
223 + 31570873 = 31571096
229 + 31570867 = 31571096
577 + 31570519 = 31571096

Showing the first eight; more decompositions exist.
