Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525458, here are decompositions:

19 + 525439 = 525458
61 + 525397 = 525458
67 + 525391 = 525458
79 + 525379 = 525458
97 + 525361 = 525458
211 + 525247 = 525458
331 + 525127 = 525458
457 + 525001 = 525458

Showing the first eight; more decompositions exist.
