Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466474, here are decompositions:

73 + 31466401 = 31466474
211 + 31466263 = 31466474
223 + 31466251 = 31466474
241 + 31466233 = 31466474
331 + 31466143 = 31466474
337 + 31466137 = 31466474
367 + 31466107 = 31466474
373 + 31466101 = 31466474

Showing the first eight; more decompositions exist.
