Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467136, here are decompositions:

3 + 31467133 = 31467136
47 + 31467089 = 31467136
53 + 31467083 = 31467136
137 + 31466999 = 31467136
167 + 31466969 = 31467136
263 + 31466873 = 31467136
269 + 31466867 = 31467136
383 + 31466753 = 31467136

Showing the first eight; more decompositions exist.
