Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548496, here are decompositions:

29 + 31548467 = 31548496
53 + 31548443 = 31548496
173 + 31548323 = 31548496
197 + 31548299 = 31548496
227 + 31548269 = 31548496
233 + 31548263 = 31548496
347 + 31548149 = 31548496
449 + 31548047 = 31548496

Showing the first eight; more decompositions exist.
