Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467160, here are decompositions:

3 + 31467157 = 31467160
71 + 31467089 = 31467160
89 + 31467071 = 31467160
149 + 31467011 = 31467160
167 + 31466993 = 31467160
191 + 31466969 = 31467160
227 + 31466933 = 31467160
293 + 31466867 = 31467160

Showing the first eight; more decompositions exist.
