Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460268, here are decompositions:

5 + 31460263 = 31460268
71 + 31460197 = 31460268
101 + 31460167 = 31460268
131 + 31460137 = 31460268
139 + 31460129 = 31460268
251 + 31460017 = 31460268
269 + 31459999 = 31460268
331 + 31459937 = 31460268

Showing the first eight; more decompositions exist.
