Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557800, here are decompositions:

11 + 33557789 = 33557800
47 + 33557753 = 33557800
71 + 33557729 = 33557800
137 + 33557663 = 33557800
173 + 33557627 = 33557800
197 + 33557603 = 33557800
233 + 33557567 = 33557800
239 + 33557561 = 33557800

Showing the first eight; more decompositions exist.
