Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532096, here are decompositions:

7 + 31532089 = 31532096
283 + 31531813 = 31532096
457 + 31531639 = 31532096
613 + 31531483 = 31532096
643 + 31531453 = 31532096
727 + 31531369 = 31532096
823 + 31531273 = 31532096
829 + 31531267 = 31532096

Showing the first eight; more decompositions exist.
