Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467268, here are decompositions:

17 + 31467251 = 31467268
101 + 31467167 = 31467268
179 + 31467089 = 31467268
197 + 31467071 = 31467268
257 + 31467011 = 31467268
269 + 31466999 = 31467268
317 + 31466951 = 31467268
401 + 31466867 = 31467268

Showing the first eight; more decompositions exist.
