Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33528972, here are decompositions:

11 + 33528961 = 33528972
19 + 33528953 = 33528972
31 + 33528941 = 33528972
41 + 33528931 = 33528972
89 + 33528883 = 33528972
131 + 33528841 = 33528972
149 + 33528823 = 33528972
151 + 33528821 = 33528972

Showing the first eight; more decompositions exist.
