Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525390, here are decompositions:

11 + 525379 = 525390
13 + 525377 = 525390
17 + 525373 = 525390
29 + 525361 = 525390
31 + 525359 = 525390
37 + 525353 = 525390
137 + 525253 = 525390
149 + 525241 = 525390

Showing the first eight; more decompositions exist.
