Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466940, here are decompositions:

7 + 31466933 = 31466940
41 + 31466899 = 31466940
47 + 31466893 = 31466940
67 + 31466873 = 31466940
73 + 31466867 = 31466940
83 + 31466857 = 31466940
149 + 31466791 = 31466940
181 + 31466759 = 31466940

Showing the first eight; more decompositions exist.
