Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571050, here are decompositions:

3 + 31571047 = 31571050
11 + 31571039 = 31571050
29 + 31571021 = 31571050
41 + 31571009 = 31571050
53 + 31570997 = 31571050
89 + 31570961 = 31571050
101 + 31570949 = 31571050
131 + 31570919 = 31571050

Showing the first eight; more decompositions exist.
