Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608822, here are decompositions:

5 + 31608817 = 31608822
29 + 31608793 = 31608822
43 + 31608779 = 31608822
73 + 31608749 = 31608822
101 + 31608721 = 31608822
109 + 31608713 = 31608822
233 + 31608589 = 31608822
293 + 31608529 = 31608822

Showing the first eight; more decompositions exist.
