Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525408, here are decompositions:

11 + 525397 = 525408
17 + 525391 = 525408
29 + 525379 = 525408
31 + 525377 = 525408
47 + 525361 = 525408
109 + 525299 = 525408
151 + 525257 = 525408
167 + 525241 = 525408

Showing the first eight; more decompositions exist.
