Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525564, here are decompositions:

23 + 525541 = 525564
31 + 525533 = 525564
47 + 525517 = 525564
71 + 525493 = 525564
73 + 525491 = 525564
97 + 525467 = 525564
103 + 525461 = 525564
107 + 525457 = 525564

Showing the first eight; more decompositions exist.
