Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466982, here are decompositions:

5 + 31466977 = 31466982
13 + 31466969 = 31466982
31 + 31466951 = 31466982
83 + 31466899 = 31466982
89 + 31466893 = 31466982
109 + 31466873 = 31466982
191 + 31466791 = 31466982
223 + 31466759 = 31466982

Showing the first eight; more decompositions exist.
