Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575058, here are decompositions:

17 + 31575041 = 31575058
59 + 31574999 = 31575058
89 + 31574969 = 31575058
131 + 31574927 = 31575058
167 + 31574891 = 31575058
197 + 31574861 = 31575058
311 + 31574747 = 31575058
401 + 31574657 = 31575058

Showing the first eight; more decompositions exist.
