Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525724, here are decompositions:

5 + 525719 = 525724
11 + 525713 = 525724
47 + 525677 = 525724
53 + 525671 = 525724
83 + 525641 = 525724
131 + 525593 = 525724
191 + 525533 = 525724
233 + 525491 = 525724

Showing the first eight; more decompositions exist.
