Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521800, here are decompositions:

3 + 33521797 = 33521800
17 + 33521783 = 33521800
41 + 33521759 = 33521800
47 + 33521753 = 33521800
71 + 33521729 = 33521800
89 + 33521711 = 33521800
107 + 33521693 = 33521800
251 + 33521549 = 33521800

Showing the first eight; more decompositions exist.
