Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528990, here are decompositions:

29 + 33528961 = 33528990
37 + 33528953 = 33528990
59 + 33528931 = 33528990
107 + 33528883 = 33528990
149 + 33528841 = 33528990
151 + 33528839 = 33528990
167 + 33528823 = 33528990
193 + 33528797 = 33528990

Showing the first eight; more decompositions exist.
