Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460488, here are decompositions:

5 + 31460483 = 31460488
47 + 31460441 = 31460488
89 + 31460399 = 31460488
149 + 31460339 = 31460488
167 + 31460321 = 31460488
197 + 31460291 = 31460488
359 + 31460129 = 31460488
557 + 31459931 = 31460488

Showing the first eight; more decompositions exist.
