Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467184, here are decompositions:

3 + 31467181 = 31467184
17 + 31467167 = 31467184
101 + 31467083 = 31467184
113 + 31467071 = 31467184
173 + 31467011 = 31467184
191 + 31466993 = 31467184
233 + 31466951 = 31467184
251 + 31466933 = 31467184

Showing the first eight; more decompositions exist.
