Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532106, here are decompositions:

17 + 31532089 = 31532106
43 + 31532063 = 31532106
103 + 31532003 = 31532106
139 + 31531967 = 31532106
197 + 31531909 = 31532106
223 + 31531883 = 31532106
293 + 31531813 = 31532106
379 + 31531727 = 31532106

Showing the first eight; more decompositions exist.
