Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532456, here are decompositions:

19 + 31532437 = 31532456
103 + 31532353 = 31532456
127 + 31532329 = 31532456
229 + 31532227 = 31532456
367 + 31532089 = 31532456
547 + 31531909 = 31532456
643 + 31531813 = 31532456
829 + 31531627 = 31532456

Showing the first eight; more decompositions exist.
