Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466468, here are decompositions:

67 + 31466401 = 31466468
79 + 31466389 = 31466468
127 + 31466341 = 31466468
139 + 31466329 = 31466468
181 + 31466287 = 31466468
211 + 31466257 = 31466468
331 + 31466137 = 31466468
349 + 31466119 = 31466468

Showing the first eight; more decompositions exist.
