Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529872, here are decompositions:

11 + 33529861 = 33529872
53 + 33529819 = 33529872
83 + 33529789 = 33529872
151 + 33529721 = 33529872
263 + 33529609 = 33529872
269 + 33529603 = 33529872
331 + 33529541 = 33529872
433 + 33529439 = 33529872

Showing the first eight; more decompositions exist.
