Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534882, here are decompositions:

3 + 31534879 = 31534882
11 + 31534871 = 31534882
83 + 31534799 = 31534882
131 + 31534751 = 31534882
173 + 31534709 = 31534882
191 + 31534691 = 31534882
251 + 31534631 = 31534882
293 + 31534589 = 31534882

Showing the first eight; more decompositions exist.
