Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525928, here are decompositions:

5 + 525923 = 525928
41 + 525887 = 525928
59 + 525869 = 525928
89 + 525839 = 525928
197 + 525731 = 525928
251 + 525677 = 525928
257 + 525671 = 525928
461 + 525467 = 525928

Showing the first eight; more decompositions exist.
