Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467352, here are decompositions:

5 + 31467347 = 31467352
23 + 31467329 = 31467352
41 + 31467311 = 31467352
101 + 31467251 = 31467352
149 + 31467203 = 31467352
263 + 31467089 = 31467352
269 + 31467083 = 31467352
281 + 31467071 = 31467352

Showing the first eight; more decompositions exist.
