Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525828, here are decompositions:

11 + 525817 = 525828
19 + 525809 = 525828
47 + 525781 = 525828
59 + 525769 = 525828
89 + 525739 = 525828
97 + 525731 = 525828
101 + 525727 = 525828
109 + 525719 = 525828

Showing the first eight; more decompositions exist.
