Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482048, here are decompositions:

5 + 31482043 = 31482048
7 + 31482041 = 31482048
11 + 31482037 = 31482048
67 + 31481981 = 31482048
97 + 31481951 = 31482048
109 + 31481939 = 31482048
127 + 31481921 = 31482048
137 + 31481911 = 31482048

Showing the first eight; more decompositions exist.
