Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466444, here are decompositions:

43 + 31466401 = 31466444
103 + 31466341 = 31466444
157 + 31466287 = 31466444
181 + 31466263 = 31466444
193 + 31466251 = 31466444
211 + 31466233 = 31466444
223 + 31466221 = 31466444
271 + 31466173 = 31466444

Showing the first eight; more decompositions exist.
