Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525526, here are decompositions:

59 + 525467 = 525526
149 + 525377 = 525526
167 + 525359 = 525526
173 + 525353 = 525526
227 + 525299 = 525526
269 + 525257 = 525526
317 + 525209 = 525526
359 + 525167 = 525526

Showing the first eight; more decompositions exist.
