Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548306, here are decompositions:

5 + 31548301 = 31548306
7 + 31548299 = 31548306
19 + 31548287 = 31548306
37 + 31548269 = 31548306
43 + 31548263 = 31548306
157 + 31548149 = 31548306
173 + 31548133 = 31548306
197 + 31548109 = 31548306

Showing the first eight; more decompositions exist.
