Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466522, here are decompositions:

19 + 31466503 = 31466522
181 + 31466341 = 31466522
193 + 31466329 = 31466522
271 + 31466251 = 31466522
349 + 31466173 = 31466522
379 + 31466143 = 31466522
421 + 31466101 = 31466522
433 + 31466089 = 31466522

Showing the first eight; more decompositions exist.
