Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482050, here are decompositions:

3 + 31482047 = 31482050
7 + 31482043 = 31482050
13 + 31482037 = 31482050
37 + 31482013 = 31482050
139 + 31481911 = 31482050
151 + 31481899 = 31482050
163 + 31481887 = 31482050
199 + 31481851 = 31482050

Showing the first eight; more decompositions exist.
