Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548522, here are decompositions:

23 + 31548499 = 31548522
79 + 31548443 = 31548522
179 + 31548343 = 31548522
191 + 31548331 = 31548522
199 + 31548323 = 31548522
223 + 31548299 = 31548522
241 + 31548281 = 31548522
373 + 31548149 = 31548522

Showing the first eight; more decompositions exist.
