Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528978, here are decompositions:

17 + 33528961 = 33528978
37 + 33528941 = 33528978
47 + 33528931 = 33528978
137 + 33528841 = 33528978
139 + 33528839 = 33528978
149 + 33528829 = 33528978
157 + 33528821 = 33528978
181 + 33528797 = 33528978

Showing the first eight; more decompositions exist.
