Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606978, here are decompositions:

5 + 33606973 = 33606978
11 + 33606967 = 33606978
19 + 33606959 = 33606978
37 + 33606941 = 33606978
59 + 33606919 = 33606978
61 + 33606917 = 33606978
71 + 33606907 = 33606978
79 + 33606899 = 33606978

Showing the first eight; more decompositions exist.
