Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597048, here are decompositions:

5 + 31597043 = 31597048
17 + 31597031 = 31597048
71 + 31596977 = 31597048
149 + 31596899 = 31597048
167 + 31596881 = 31597048
191 + 31596857 = 31597048
227 + 31596821 = 31597048
251 + 31596797 = 31597048

Showing the first eight; more decompositions exist.
