Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467306, here are decompositions:

5 + 31467301 = 31467306
47 + 31467259 = 31467306
103 + 31467203 = 31467306
107 + 31467199 = 31467306
137 + 31467169 = 31467306
139 + 31467167 = 31467306
149 + 31467157 = 31467306
173 + 31467133 = 31467306

Showing the first eight; more decompositions exist.
