Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466610, here are decompositions:

13 + 31466597 = 31466610
23 + 31466587 = 31466610
47 + 31466563 = 31466610
61 + 31466549 = 31466610
107 + 31466503 = 31466610
223 + 31466387 = 31466610
229 + 31466381 = 31466610
269 + 31466341 = 31466610

Showing the first eight; more decompositions exist.
