Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525856, here are decompositions:

17 + 525839 = 525856
47 + 525809 = 525856
83 + 525773 = 525856
137 + 525719 = 525856
179 + 525677 = 525856
257 + 525599 = 525856
263 + 525593 = 525856
389 + 525467 = 525856

Showing the first eight; more decompositions exist.
