Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466408, here are decompositions:

7 + 31466401 = 31466408
19 + 31466389 = 31466408
67 + 31466341 = 31466408
79 + 31466329 = 31466408
151 + 31466257 = 31466408
157 + 31466251 = 31466408
271 + 31466137 = 31466408
307 + 31466101 = 31466408

Showing the first eight; more decompositions exist.
