Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571314, here are decompositions:

11 + 31571303 = 31571314
101 + 31571213 = 31571314
107 + 31571207 = 31571314
113 + 31571201 = 31571314
167 + 31571147 = 31571314
233 + 31571081 = 31571314
251 + 31571063 = 31571314
293 + 31571021 = 31571314

Showing the first eight; more decompositions exist.
