Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525406, here are decompositions:

29 + 525377 = 525406
47 + 525359 = 525406
53 + 525353 = 525406
107 + 525299 = 525406
149 + 525257 = 525406
197 + 525209 = 525406
239 + 525167 = 525406
263 + 525143 = 525406

Showing the first eight; more decompositions exist.
