Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499164, here are decompositions:

3 + 31499161 = 31499164
5 + 31499159 = 31499164
101 + 31499063 = 31499164
107 + 31499057 = 31499164
131 + 31499033 = 31499164
173 + 31498991 = 31499164
197 + 31498967 = 31499164
233 + 31498931 = 31499164

Showing the first eight; more decompositions exist.
