Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543920, here are decompositions:

19 + 33543901 = 33543920
43 + 33543877 = 33543920
79 + 33543841 = 33543920
211 + 33543709 = 33543920
271 + 33543649 = 33543920
337 + 33543583 = 33543920
367 + 33543553 = 33543920
373 + 33543547 = 33543920

Showing the first eight; more decompositions exist.
