Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542800, here are decompositions:

17 + 33542783 = 33542800
23 + 33542777 = 33542800
41 + 33542759 = 33542800
47 + 33542753 = 33542800
89 + 33542711 = 33542800
197 + 33542603 = 33542800
227 + 33542573 = 33542800
233 + 33542567 = 33542800

Showing the first eight; more decompositions exist.
