Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33501978, here are decompositions:

7 + 33501971 = 33501978
71 + 33501907 = 33501978
89 + 33501889 = 33501978
137 + 33501841 = 33501978
179 + 33501799 = 33501978
199 + 33501779 = 33501978
227 + 33501751 = 33501978
241 + 33501737 = 33501978

Showing the first eight; more decompositions exist.
