Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525550, here are decompositions:

17 + 525533 = 525550
59 + 525491 = 525550
83 + 525467 = 525550
89 + 525461 = 525550
173 + 525377 = 525550
191 + 525359 = 525550
197 + 525353 = 525550
251 + 525299 = 525550

Showing the first eight; more decompositions exist.
