Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523164, here are decompositions:

3 + 31523161 = 31523164
53 + 31523111 = 31523164
83 + 31523081 = 31523164
137 + 31523027 = 31523164
227 + 31522937 = 31523164
263 + 31522901 = 31523164
317 + 31522847 = 31523164
641 + 31522523 = 31523164

Showing the first eight; more decompositions exist.
