Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463864, here are decompositions:

7 + 31463857 = 31463864
37 + 31463827 = 31463864
67 + 31463797 = 31463864
97 + 31463767 = 31463864
151 + 31463713 = 31463864
277 + 31463587 = 31463864
331 + 31463533 = 31463864
337 + 31463527 = 31463864

Showing the first eight; more decompositions exist.
