Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463896, here are decompositions:

3 + 31463893 = 31463896
5 + 31463891 = 31463896
17 + 31463879 = 31463896
47 + 31463849 = 31463896
53 + 31463843 = 31463896
89 + 31463807 = 31463896
137 + 31463759 = 31463896
179 + 31463717 = 31463896

Showing the first eight; more decompositions exist.
