Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463910, here are decompositions:

13 + 31463897 = 31463910
17 + 31463893 = 31463910
19 + 31463891 = 31463910
31 + 31463879 = 31463910
53 + 31463857 = 31463910
61 + 31463849 = 31463910
67 + 31463843 = 31463910
83 + 31463827 = 31463910

Showing the first eight; more decompositions exist.
