Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463966, here are decompositions:

3 + 31463963 = 31463966
7 + 31463959 = 31463966
73 + 31463893 = 31463966
109 + 31463857 = 31463966
139 + 31463827 = 31463966
199 + 31463767 = 31463966
223 + 31463743 = 31463966
277 + 31463689 = 31463966

Showing the first eight; more decompositions exist.
