Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478296, here are decompositions:

29 + 31478267 = 31478296
107 + 31478189 = 31478296
149 + 31478147 = 31478296
167 + 31478129 = 31478296
359 + 31477937 = 31478296
389 + 31477907 = 31478296
419 + 31477877 = 31478296
503 + 31477793 = 31478296

Showing the first eight; more decompositions exist.
