Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608834, here are decompositions:

11 + 31608823 = 31608834
13 + 31608821 = 31608834
17 + 31608817 = 31608834
41 + 31608793 = 31608834
97 + 31608737 = 31608834
107 + 31608727 = 31608834
113 + 31608721 = 31608834
137 + 31608697 = 31608834

Showing the first eight; more decompositions exist.
