Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575352, here are decompositions:

41 + 31575311 = 31575352
71 + 31575281 = 31575352
131 + 31575221 = 31575352
191 + 31575161 = 31575352
293 + 31575059 = 31575352
311 + 31575041 = 31575352
353 + 31574999 = 31575352
383 + 31574969 = 31575352

Showing the first eight; more decompositions exist.
