Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525824, here are decompositions:

7 + 525817 = 525824
43 + 525781 = 525824
97 + 525727 = 525824
127 + 525697 = 525824
241 + 525583 = 525824
283 + 525541 = 525824
307 + 525517 = 525824
331 + 525493 = 525824

Showing the first eight; more decompositions exist.
