Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548322, here are decompositions:

23 + 31548299 = 31548322
41 + 31548281 = 31548322
53 + 31548269 = 31548322
59 + 31548263 = 31548322
173 + 31548149 = 31548322
293 + 31548029 = 31548322
389 + 31547933 = 31548322
401 + 31547921 = 31548322

Showing the first eight; more decompositions exist.
