Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525600, here are decompositions:

7 + 525593 = 525600
17 + 525583 = 525600
29 + 525571 = 525600
59 + 525541 = 525600
67 + 525533 = 525600
71 + 525529 = 525600
83 + 525517 = 525600
107 + 525493 = 525600

Showing the first eight; more decompositions exist.
