Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460274, here are decompositions:

7 + 31460267 = 31460274
11 + 31460263 = 31460274
101 + 31460173 = 31460274
107 + 31460167 = 31460274
137 + 31460137 = 31460274
211 + 31460063 = 31460274
257 + 31460017 = 31460274
281 + 31459993 = 31460274

Showing the first eight; more decompositions exist.
