Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482088, here are decompositions:

5 + 31482083 = 31482088
41 + 31482047 = 31482088
47 + 31482041 = 31482088
107 + 31481981 = 31482088
137 + 31481951 = 31482088
149 + 31481939 = 31482088
167 + 31481921 = 31482088
251 + 31481837 = 31482088

Showing the first eight; more decompositions exist.
