Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505978, here are decompositions:

17 + 33505961 = 33505978
71 + 33505907 = 33505978
89 + 33505889 = 33505978
131 + 33505847 = 33505978
179 + 33505799 = 33505978
197 + 33505781 = 33505978
227 + 33505751 = 33505978
347 + 33505631 = 33505978

Showing the first eight; more decompositions exist.
