Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525398, here are decompositions:

7 + 525391 = 525398
19 + 525379 = 525398
37 + 525361 = 525398
151 + 525247 = 525398
157 + 525241 = 525398
199 + 525199 = 525398
241 + 525157 = 525398
271 + 525127 = 525398

Showing the first eight; more decompositions exist.
