Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608024, here are decompositions:

11 + 31608013 = 31608024
53 + 31607971 = 31608024
103 + 31607921 = 31608024
127 + 31607897 = 31608024
157 + 31607867 = 31608024
167 + 31607857 = 31608024
193 + 31607831 = 31608024
233 + 31607791 = 31608024

Showing the first eight; more decompositions exist.
