Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476628, here are decompositions:

5 + 31476623 = 31476628
17 + 31476611 = 31476628
41 + 31476587 = 31476628
167 + 31476461 = 31476628
179 + 31476449 = 31476628
191 + 31476437 = 31476628
257 + 31476371 = 31476628
311 + 31476317 = 31476628

Showing the first eight; more decompositions exist.
