Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33978, here are decompositions:

11 + 33967 = 33978
17 + 33961 = 33978
37 + 33941 = 33978
41 + 33937 = 33978
47 + 33931 = 33978
67 + 33911 = 33978
89 + 33889 = 33978
107 + 33871 = 33978

Showing the first eight; more decompositions exist.
