Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521592, here are decompositions:

11 + 521581 = 521592
41 + 521551 = 521592
53 + 521539 = 521592
59 + 521533 = 521592
73 + 521519 = 521592
89 + 521503 = 521592
101 + 521491 = 521592
109 + 521483 = 521592

Showing the first eight; more decompositions exist.
