Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521920, here are decompositions:

17 + 33521903 = 33521920
59 + 33521861 = 33521920
137 + 33521783 = 33521920
167 + 33521753 = 33521920
191 + 33521729 = 33521920
227 + 33521693 = 33521920
389 + 33521531 = 33521920
449 + 33521471 = 33521920

Showing the first eight; more decompositions exist.
