Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548348, here are decompositions:

5 + 31548343 = 31548348
17 + 31548331 = 31548348
47 + 31548301 = 31548348
61 + 31548287 = 31548348
67 + 31548281 = 31548348
79 + 31548269 = 31548348
199 + 31548149 = 31548348
239 + 31548109 = 31548348

Showing the first eight; more decompositions exist.
