Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452252, here are decompositions:

11 + 31452241 = 31452252
19 + 31452233 = 31452252
43 + 31452209 = 31452252
53 + 31452199 = 31452252
71 + 31452181 = 31452252
79 + 31452173 = 31452252
131 + 31452121 = 31452252
163 + 31452089 = 31452252

Showing the first eight; more decompositions exist.
