Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466456, here are decompositions:

67 + 31466389 = 31466456
127 + 31466329 = 31466456
193 + 31466263 = 31466456
199 + 31466257 = 31466456
223 + 31466233 = 31466456
283 + 31466173 = 31466456
313 + 31466143 = 31466456
337 + 31466119 = 31466456

Showing the first eight; more decompositions exist.
