Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467274, here are decompositions:

23 + 31467251 = 31467274
71 + 31467203 = 31467274
107 + 31467167 = 31467274
191 + 31467083 = 31467274
263 + 31467011 = 31467274
281 + 31466993 = 31467274
401 + 31466873 = 31467274
521 + 31466753 = 31467274

Showing the first eight; more decompositions exist.
