Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467208, here are decompositions:

5 + 31467203 = 31467208
41 + 31467167 = 31467208
137 + 31467071 = 31467208
197 + 31467011 = 31467208
239 + 31466969 = 31467208
257 + 31466951 = 31467208
359 + 31466849 = 31467208
449 + 31466759 = 31467208

Showing the first eight; more decompositions exist.
