Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548292, here are decompositions:

5 + 31548287 = 31548292
11 + 31548281 = 31548292
23 + 31548269 = 31548292
29 + 31548263 = 31548292
263 + 31548029 = 31548292
311 + 31547981 = 31548292
359 + 31547933 = 31548292
431 + 31547861 = 31548292

Showing the first eight; more decompositions exist.
