Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572058, here are decompositions:

17 + 31572041 = 31572058
29 + 31572029 = 31572058
41 + 31572017 = 31572058
101 + 31571957 = 31572058
179 + 31571879 = 31572058
191 + 31571867 = 31572058
281 + 31571777 = 31572058
311 + 31571747 = 31572058

Showing the first eight; more decompositions exist.
