Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463968, here are decompositions:

5 + 31463963 = 31463968
47 + 31463921 = 31463968
59 + 31463909 = 31463968
71 + 31463897 = 31463968
89 + 31463879 = 31463968
251 + 31463717 = 31463968
449 + 31463519 = 31463968
461 + 31463507 = 31463968

Showing the first eight; more decompositions exist.
