Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482148, here are decompositions:

29 + 31482119 = 31482148
59 + 31482089 = 31482148
101 + 31482047 = 31482148
107 + 31482041 = 31482148
167 + 31481981 = 31482148
197 + 31481951 = 31482148
227 + 31481921 = 31482148
281 + 31481867 = 31482148

Showing the first eight; more decompositions exist.
