Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467392, here are decompositions:

3 + 31467389 = 31467392
163 + 31467229 = 31467392
193 + 31467199 = 31467392
211 + 31467181 = 31467392
223 + 31467169 = 31467392
499 + 31466893 = 31467392
571 + 31466821 = 31467392
601 + 31466791 = 31467392

Showing the first eight; more decompositions exist.
