Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525826, here are decompositions:

17 + 525809 = 525826
53 + 525773 = 525826
107 + 525719 = 525826
113 + 525713 = 525826
149 + 525677 = 525826
227 + 525599 = 525826
233 + 525593 = 525826
293 + 525533 = 525826

Showing the first eight; more decompositions exist.
