Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463958, here are decompositions:

17 + 31463941 = 31463958
37 + 31463921 = 31463958
47 + 31463911 = 31463958
61 + 31463897 = 31463958
67 + 31463891 = 31463958
79 + 31463879 = 31463958
101 + 31463857 = 31463958
109 + 31463849 = 31463958

Showing the first eight; more decompositions exist.
