Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525438, here are decompositions:

5 + 525433 = 525438
7 + 525431 = 525438
29 + 525409 = 525438
41 + 525397 = 525438
47 + 525391 = 525438
59 + 525379 = 525438
61 + 525377 = 525438
79 + 525359 = 525438

Showing the first eight; more decompositions exist.
