Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521576, here are decompositions:

19 + 521557 = 521576
37 + 521539 = 521576
43 + 521533 = 521576
73 + 521503 = 521576
79 + 521497 = 521576
199 + 521377 = 521576
277 + 521299 = 521576
397 + 521179 = 521576

Showing the first eight; more decompositions exist.
