Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33607978, here are decompositions:

11 + 33607967 = 33607978
29 + 33607949 = 33607978
71 + 33607907 = 33607978
137 + 33607841 = 33607978
251 + 33607727 = 33607978
281 + 33607697 = 33607978
359 + 33607619 = 33607978
431 + 33607547 = 33607978

Showing the first eight; more decompositions exist.
