Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525394, here are decompositions:

3 + 525391 = 525394
17 + 525377 = 525394
41 + 525353 = 525394
137 + 525257 = 525394
173 + 525221 = 525394
227 + 525167 = 525394
251 + 525143 = 525394
257 + 525137 = 525394

Showing the first eight; more decompositions exist.
