Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533252, here are decompositions:

43 + 31533209 = 31533252
61 + 31533191 = 31533252
103 + 31533149 = 31533252
109 + 31533143 = 31533252
151 + 31533101 = 31533252
239 + 31533013 = 31533252
251 + 31533001 = 31533252
271 + 31532981 = 31533252

Showing the first eight; more decompositions exist.
