Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532352, here are decompositions:

11 + 31532341 = 31532352
13 + 31532339 = 31532352
23 + 31532329 = 31532352
29 + 31532323 = 31532352
73 + 31532279 = 31532352
83 + 31532269 = 31532352
149 + 31532203 = 31532352
211 + 31532141 = 31532352

Showing the first eight; more decompositions exist.
