Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463916, here are decompositions:

5 + 31463911 = 31463916
7 + 31463909 = 31463916
19 + 31463897 = 31463916
23 + 31463893 = 31463916
37 + 31463879 = 31463916
59 + 31463857 = 31463916
67 + 31463849 = 31463916
73 + 31463843 = 31463916

Showing the first eight; more decompositions exist.
