Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529472, here are decompositions:

103 + 33529369 = 33529472
181 + 33529291 = 33529472
313 + 33529159 = 33529472
349 + 33529123 = 33529472
541 + 33528931 = 33529472
631 + 33528841 = 33529472
643 + 33528829 = 33529472
733 + 33528739 = 33529472

Showing the first eight; more decompositions exist.
