Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521824, here are decompositions:

5 + 521819 = 521824
11 + 521813 = 521824
47 + 521777 = 521824
71 + 521753 = 521824
101 + 521723 = 521824
131 + 521693 = 521824
167 + 521657 = 521824
257 + 521567 = 521824

Showing the first eight; more decompositions exist.
