Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525748, here are decompositions:

17 + 525731 = 525748
29 + 525719 = 525748
71 + 525677 = 525748
107 + 525641 = 525748
149 + 525599 = 525748
257 + 525491 = 525748
281 + 525467 = 525748
317 + 525431 = 525748

Showing the first eight; more decompositions exist.
