Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467400, here are decompositions:

11 + 31467389 = 31467400
53 + 31467347 = 31467400
71 + 31467329 = 31467400
89 + 31467311 = 31467400
149 + 31467251 = 31467400
197 + 31467203 = 31467400
233 + 31467167 = 31467400
311 + 31467089 = 31467400

Showing the first eight; more decompositions exist.
