Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532232, here are decompositions:

5 + 31532227 = 31532232
13 + 31532219 = 31532232
23 + 31532209 = 31532232
29 + 31532203 = 31532232
211 + 31532021 = 31532232
229 + 31532003 = 31532232
311 + 31531921 = 31532232
349 + 31531883 = 31532232

Showing the first eight; more decompositions exist.
