Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532896, here are decompositions:

23 + 31532873 = 31532896
29 + 31532867 = 31532896
257 + 31532639 = 31532896
389 + 31532507 = 31532896
419 + 31532477 = 31532896
467 + 31532429 = 31532896
557 + 31532339 = 31532896
617 + 31532279 = 31532896

Showing the first eight; more decompositions exist.
