Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525802, here are decompositions:

29 + 525773 = 525802
71 + 525731 = 525802
83 + 525719 = 525802
89 + 525713 = 525802
131 + 525671 = 525802
269 + 525533 = 525802
311 + 525491 = 525802
443 + 525359 = 525802

Showing the first eight; more decompositions exist.
