Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525524, here are decompositions:

7 + 525517 = 525524
31 + 525493 = 525524
67 + 525457 = 525524
127 + 525397 = 525524
151 + 525373 = 525524
163 + 525361 = 525524
211 + 525313 = 525524
271 + 525253 = 525524

Showing the first eight; more decompositions exist.
