Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454164, here are decompositions:

3 + 31454161 = 31454164
17 + 31454147 = 31454164
41 + 31454123 = 31454164
47 + 31454117 = 31454164
83 + 31454081 = 31454164
167 + 31453997 = 31454164
173 + 31453991 = 31454164
233 + 31453931 = 31454164

Showing the first eight; more decompositions exist.
