Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466554, here are decompositions:

5 + 31466549 = 31466554
167 + 31466387 = 31466554
173 + 31466381 = 31466554
227 + 31466327 = 31466554
263 + 31466291 = 31466554
347 + 31466207 = 31466554
491 + 31466063 = 31466554
503 + 31466051 = 31466554

Showing the first eight; more decompositions exist.
