Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571134, here are decompositions:

53 + 31571081 = 31571134
71 + 31571063 = 31571134
113 + 31571021 = 31571134
137 + 31570997 = 31571134
173 + 31570961 = 31571134
227 + 31570907 = 31571134
317 + 31570817 = 31571134
347 + 31570787 = 31571134

Showing the first eight; more decompositions exist.
