Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482172, here are decompositions:

3 + 31482169 = 31482172
5 + 31482167 = 31482172
53 + 31482119 = 31482172
83 + 31482089 = 31482172
89 + 31482083 = 31482172
131 + 31482041 = 31482172
191 + 31481981 = 31482172
233 + 31481939 = 31482172

Showing the first eight; more decompositions exist.
