Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548882, here are decompositions:

11 + 31548871 = 31548882
59 + 31548823 = 31548882
139 + 31548743 = 31548882
149 + 31548733 = 31548882
223 + 31548659 = 31548882
229 + 31548653 = 31548882
241 + 31548641 = 31548882
263 + 31548619 = 31548882

Showing the first eight; more decompositions exist.
