Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529180, here are decompositions:

23 + 33529157 = 33529180
71 + 33529109 = 33529180
101 + 33529079 = 33529180
137 + 33529043 = 33529180
149 + 33529031 = 33529180
227 + 33528953 = 33529180
239 + 33528941 = 33529180
359 + 33528821 = 33529180

Showing the first eight; more decompositions exist.
