Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571276, here are decompositions:

19 + 31571257 = 31571276
109 + 31571167 = 31571276
127 + 31571149 = 31571276
193 + 31571083 = 31571276
229 + 31571047 = 31571276
277 + 31570999 = 31571276
283 + 31570993 = 31571276
337 + 31570939 = 31571276

Showing the first eight; more decompositions exist.
