Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466552, here are decompositions:

3 + 31466549 = 31466552
151 + 31466401 = 31466552
163 + 31466389 = 31466552
211 + 31466341 = 31466552
223 + 31466329 = 31466552
331 + 31466221 = 31466552
379 + 31466173 = 31466552
409 + 31466143 = 31466552

Showing the first eight; more decompositions exist.
