Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463976, here are decompositions:

13 + 31463963 = 31463976
17 + 31463959 = 31463976
67 + 31463909 = 31463976
79 + 31463897 = 31463976
83 + 31463893 = 31463976
97 + 31463879 = 31463976
127 + 31463849 = 31463976
149 + 31463827 = 31463976

Showing the first eight; more decompositions exist.
