Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466682, here are decompositions:

11 + 31466671 = 31466682
53 + 31466629 = 31466682
179 + 31466503 = 31466682
281 + 31466401 = 31466682
293 + 31466389 = 31466682
353 + 31466329 = 31466682
419 + 31466263 = 31466682
431 + 31466251 = 31466682

Showing the first eight; more decompositions exist.
