Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521808, here are decompositions:

11 + 33521797 = 33521808
79 + 33521729 = 33521808
97 + 33521711 = 33521808
107 + 33521701 = 33521808
179 + 33521629 = 33521808
269 + 33521539 = 33521808
277 + 33521531 = 33521808
337 + 33521471 = 33521808

Showing the first eight; more decompositions exist.
