Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532256, here are decompositions:

29 + 31532227 = 31532256
37 + 31532219 = 31532256
47 + 31532209 = 31532256
53 + 31532203 = 31532256
89 + 31532167 = 31532256
139 + 31532117 = 31532256
167 + 31532089 = 31532256
193 + 31532063 = 31532256

Showing the first eight; more decompositions exist.
