Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525688, here are decompositions:

11 + 525677 = 525688
17 + 525671 = 525688
47 + 525641 = 525688
89 + 525599 = 525688
197 + 525491 = 525688
227 + 525461 = 525688
257 + 525431 = 525688
311 + 525377 = 525688

Showing the first eight; more decompositions exist.
