Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596912, here are decompositions:

5 + 31596907 = 31596912
13 + 31596899 = 31596912
23 + 31596889 = 31596912
29 + 31596883 = 31596912
31 + 31596881 = 31596912
73 + 31596839 = 31596912
163 + 31596749 = 31596912
199 + 31596713 = 31596912

Showing the first eight; more decompositions exist.
