Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543164, here are decompositions:

31 + 31543133 = 31543164
61 + 31543103 = 31543164
97 + 31543067 = 31543164
173 + 31542991 = 31543164
193 + 31542971 = 31543164
197 + 31542967 = 31543164
223 + 31542941 = 31543164
227 + 31542937 = 31543164

Showing the first eight; more decompositions exist.
