Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608922, here are decompositions:

5 + 31608917 = 31608922
11 + 31608911 = 31608922
29 + 31608893 = 31608922
71 + 31608851 = 31608922
101 + 31608821 = 31608922
173 + 31608749 = 31608922
659 + 31608263 = 31608922
773 + 31608149 = 31608922

Showing the first eight; more decompositions exist.
