Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532432, here are decompositions:

3 + 31532429 = 31532432
31 + 31532401 = 31532432
79 + 31532353 = 31532432
103 + 31532329 = 31532432
109 + 31532323 = 31532432
163 + 31532269 = 31532432
223 + 31532209 = 31532432
229 + 31532203 = 31532432

Showing the first eight; more decompositions exist.
