Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536438, here are decompositions:

31 + 536407 = 536438
61 + 536377 = 536438
127 + 536311 = 536438
151 + 536287 = 536438
157 + 536281 = 536438
211 + 536227 = 536438
337 + 536101 = 536438
379 + 536059 = 536438

Showing the first eight; more decompositions exist.
