Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482132, here are decompositions:

13 + 31482119 = 31482132
29 + 31482103 = 31482132
43 + 31482089 = 31482132
89 + 31482043 = 31482132
151 + 31481981 = 31482132
181 + 31481951 = 31482132
193 + 31481939 = 31482132
211 + 31481921 = 31482132

Showing the first eight; more decompositions exist.
