Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571092, here are decompositions:

11 + 31571081 = 31571092
29 + 31571063 = 31571092
53 + 31571039 = 31571092
71 + 31571021 = 31571092
83 + 31571009 = 31571092
131 + 31570961 = 31571092
173 + 31570919 = 31571092
233 + 31570859 = 31571092

Showing the first eight; more decompositions exist.
