Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473978, here are decompositions:

7 + 33473971 = 33473978
37 + 33473941 = 33473978
157 + 33473821 = 33473978
199 + 33473779 = 33473978
211 + 33473767 = 33473978
229 + 33473749 = 33473978
379 + 33473599 = 33473978
541 + 33473437 = 33473978

Showing the first eight; more decompositions exist.
