Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463814, here are decompositions:

7 + 31463807 = 31463814
17 + 31463797 = 31463814
47 + 31463767 = 31463814
71 + 31463743 = 31463814
97 + 31463717 = 31463814
101 + 31463713 = 31463814
223 + 31463591 = 31463814
227 + 31463587 = 31463814

Showing the first eight; more decompositions exist.
