Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460276, here are decompositions:

13 + 31460263 = 31460276
79 + 31460197 = 31460276
103 + 31460173 = 31460276
109 + 31460167 = 31460276
139 + 31460137 = 31460276
223 + 31460053 = 31460276
277 + 31459999 = 31460276
283 + 31459993 = 31460276

Showing the first eight; more decompositions exist.
