Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466980, here are decompositions:

3 + 31466977 = 31466980
11 + 31466969 = 31466980
29 + 31466951 = 31466980
47 + 31466933 = 31466980
107 + 31466873 = 31466980
113 + 31466867 = 31466980
131 + 31466849 = 31466980
227 + 31466753 = 31466980

Showing the first eight; more decompositions exist.
