Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463694, here are decompositions:

5 + 31463689 = 31463694
13 + 31463681 = 31463694
103 + 31463591 = 31463694
107 + 31463587 = 31463694
167 + 31463527 = 31463694
211 + 31463483 = 31463694
307 + 31463387 = 31463694
331 + 31463363 = 31463694

Showing the first eight; more decompositions exist.
