Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577978, here are decompositions:

11 + 33577967 = 33577978
41 + 33577937 = 33577978
59 + 33577919 = 33577978
89 + 33577889 = 33577978
107 + 33577871 = 33577978
131 + 33577847 = 33577978
149 + 33577829 = 33577978
197 + 33577781 = 33577978

Showing the first eight; more decompositions exist.
