Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575358, here are decompositions:

5 + 31575353 = 31575358
47 + 31575311 = 31575358
137 + 31575221 = 31575358
197 + 31575161 = 31575358
251 + 31575107 = 31575358
317 + 31575041 = 31575358
359 + 31574999 = 31575358
389 + 31574969 = 31575358

Showing the first eight; more decompositions exist.
