Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467252, here are decompositions:

23 + 31467229 = 31467252
53 + 31467199 = 31467252
71 + 31467181 = 31467252
83 + 31467169 = 31467252
149 + 31467103 = 31467252
163 + 31467089 = 31467252
181 + 31467071 = 31467252
241 + 31467011 = 31467252

Showing the first eight; more decompositions exist.
