Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468164, here are decompositions:

5 + 31468159 = 31468164
17 + 31468147 = 31468164
67 + 31468097 = 31468164
97 + 31468067 = 31468164
137 + 31468027 = 31468164
151 + 31468013 = 31468164
163 + 31468001 = 31468164
181 + 31467983 = 31468164

Showing the first eight; more decompositions exist.
