Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540164, here are decompositions:

17 + 31540147 = 31540164
41 + 31540123 = 31540164
101 + 31540063 = 31540164
151 + 31540013 = 31540164
157 + 31540007 = 31540164
193 + 31539971 = 31540164
197 + 31539967 = 31540164
233 + 31539931 = 31540164

Showing the first eight; more decompositions exist.
