Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466946, here are decompositions:

13 + 31466933 = 31466946
47 + 31466899 = 31466946
53 + 31466893 = 31466946
73 + 31466873 = 31466946
79 + 31466867 = 31466946
89 + 31466857 = 31466946
97 + 31466849 = 31466946
193 + 31466753 = 31466946

Showing the first eight; more decompositions exist.
