Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482208, here are decompositions:

29 + 31482179 = 31482208
41 + 31482167 = 31482208
89 + 31482119 = 31482208
167 + 31482041 = 31482208
227 + 31481981 = 31482208
257 + 31481951 = 31482208
269 + 31481939 = 31482208
389 + 31481819 = 31482208

Showing the first eight; more decompositions exist.
