Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575046, here are decompositions:

5 + 31575041 = 31575046
47 + 31574999 = 31575046
197 + 31574849 = 31575046
233 + 31574813 = 31575046
353 + 31574693 = 31575046
359 + 31574687 = 31575046
389 + 31574657 = 31575046
557 + 31574489 = 31575046

Showing the first eight; more decompositions exist.
