Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532164, here are decompositions:

23 + 31532141 = 31532164
47 + 31532117 = 31532164
101 + 31532063 = 31532164
197 + 31531967 = 31532164
233 + 31531931 = 31532164
281 + 31531883 = 31532164
347 + 31531817 = 31532164
641 + 31531523 = 31532164

Showing the first eight; more decompositions exist.
