Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453164, here are decompositions:

5 + 31453159 = 31453164
7 + 31453157 = 31453164
23 + 31453141 = 31453164
31 + 31453133 = 31453164
191 + 31452973 = 31453164
263 + 31452901 = 31453164
313 + 31452851 = 31453164
401 + 31452763 = 31453164

Showing the first eight; more decompositions exist.
