Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514896, here are decompositions:

3 + 31514893 = 31514896
47 + 31514849 = 31514896
59 + 31514837 = 31514896
107 + 31514789 = 31514896
113 + 31514783 = 31514896
233 + 31514663 = 31514896
269 + 31514627 = 31514896
317 + 31514579 = 31514896

Showing the first eight; more decompositions exist.
