Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626882, here are decompositions:

13 + 31626869 = 31626882
41 + 31626841 = 31626882
43 + 31626839 = 31626882
173 + 31626709 = 31626882
191 + 31626691 = 31626882
193 + 31626689 = 31626882
263 + 31626619 = 31626882
293 + 31626589 = 31626882

Showing the first eight; more decompositions exist.
