Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525420, here are decompositions:

11 + 525409 = 525420
23 + 525397 = 525420
29 + 525391 = 525420
41 + 525379 = 525420
43 + 525377 = 525420
47 + 525373 = 525420
59 + 525361 = 525420
61 + 525359 = 525420

Showing the first eight; more decompositions exist.
