Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596882, here are decompositions:

43 + 31596839 = 31596882
61 + 31596821 = 31596882
89 + 31596793 = 31596882
113 + 31596769 = 31596882
131 + 31596751 = 31596882
139 + 31596743 = 31596882
173 + 31596709 = 31596882
211 + 31596671 = 31596882

Showing the first eight; more decompositions exist.
