Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532552, here are decompositions:

13 + 31532539 = 31532552
31 + 31532521 = 31532552
151 + 31532401 = 31532552
199 + 31532353 = 31532552
211 + 31532341 = 31532552
223 + 31532329 = 31532552
229 + 31532323 = 31532552
283 + 31532269 = 31532552

Showing the first eight; more decompositions exist.
