Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467318, here are decompositions:

7 + 31467311 = 31467318
17 + 31467301 = 31467318
59 + 31467259 = 31467318
67 + 31467251 = 31467318
89 + 31467229 = 31467318
137 + 31467181 = 31467318
149 + 31467169 = 31467318
151 + 31467167 = 31467318

Showing the first eight; more decompositions exist.
