Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466562, here are decompositions:

13 + 31466549 = 31466562
59 + 31466503 = 31466562
173 + 31466389 = 31466562
181 + 31466381 = 31466562
233 + 31466329 = 31466562
271 + 31466291 = 31466562
311 + 31466251 = 31466562
313 + 31466249 = 31466562

Showing the first eight; more decompositions exist.
