Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521544, here are decompositions:

5 + 521539 = 521544
7 + 521537 = 521544
11 + 521533 = 521544
17 + 521527 = 521544
41 + 521503 = 521544
47 + 521497 = 521544
53 + 521491 = 521544
61 + 521483 = 521544

Showing the first eight; more decompositions exist.
