Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571334, here are decompositions:

7 + 31571327 = 31571334
31 + 31571303 = 31571334
127 + 31571207 = 31571334
167 + 31571167 = 31571334
191 + 31571143 = 31571334
251 + 31571083 = 31571334
271 + 31571063 = 31571334
313 + 31571021 = 31571334

Showing the first eight; more decompositions exist.
