Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548448, here are decompositions:

5 + 31548443 = 31548448
17 + 31548431 = 31548448
47 + 31548401 = 31548448
149 + 31548299 = 31548448
167 + 31548281 = 31548448
179 + 31548269 = 31548448
401 + 31548047 = 31548448
419 + 31548029 = 31548448

Showing the first eight; more decompositions exist.
