Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608964, here are decompositions:

5 + 31608959 = 31608964
11 + 31608953 = 31608964
47 + 31608917 = 31608964
53 + 31608911 = 31608964
71 + 31608893 = 31608964
113 + 31608851 = 31608964
227 + 31608737 = 31608964
251 + 31608713 = 31608964

Showing the first eight; more decompositions exist.
