Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466442, here are decompositions:

41 + 31466401 = 31466442
53 + 31466389 = 31466442
61 + 31466381 = 31466442
101 + 31466341 = 31466442
113 + 31466329 = 31466442
151 + 31466291 = 31466442
179 + 31466263 = 31466442
191 + 31466251 = 31466442

Showing the first eight; more decompositions exist.
