Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467378, here are decompositions:

11 + 31467367 = 31467378
31 + 31467347 = 31467378
67 + 31467311 = 31467378
127 + 31467251 = 31467378
149 + 31467229 = 31467378
179 + 31467199 = 31467378
197 + 31467181 = 31467378
211 + 31467167 = 31467378

Showing the first eight; more decompositions exist.
