Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529552, here are decompositions:

13 + 31529539 = 31529552
31 + 31529521 = 31529552
73 + 31529479 = 31529552
139 + 31529413 = 31529552
193 + 31529359 = 31529552
199 + 31529353 = 31529552
283 + 31529269 = 31529552
463 + 31529089 = 31529552

Showing the first eight; more decompositions exist.
