Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521872, here are decompositions:

11 + 33521861 = 33521872
29 + 33521843 = 33521872
89 + 33521783 = 33521872
113 + 33521759 = 33521872
179 + 33521693 = 33521872
389 + 33521483 = 33521872
401 + 33521471 = 33521872
479 + 33521393 = 33521872

Showing the first eight; more decompositions exist.
