Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525384, here are decompositions:

5 + 525379 = 525384
7 + 525377 = 525384
11 + 525373 = 525384
23 + 525361 = 525384
31 + 525353 = 525384
71 + 525313 = 525384
127 + 525257 = 525384
131 + 525253 = 525384

Showing the first eight; more decompositions exist.
