Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525436, here are decompositions:

3 + 525433 = 525436
5 + 525431 = 525436
59 + 525377 = 525436
83 + 525353 = 525436
137 + 525299 = 525436
179 + 525257 = 525436
227 + 525209 = 525436
269 + 525167 = 525436

Showing the first eight; more decompositions exist.
