Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525578, here are decompositions:

7 + 525571 = 525578
37 + 525541 = 525578
61 + 525517 = 525578
139 + 525439 = 525578
181 + 525397 = 525578
199 + 525379 = 525578
331 + 525247 = 525578
337 + 525241 = 525578

Showing the first eight; more decompositions exist.
