Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507900, here are decompositions:

7 + 33507893 = 33507900
11 + 33507889 = 33507900
47 + 33507853 = 33507900
79 + 33507821 = 33507900
103 + 33507797 = 33507900
137 + 33507763 = 33507900
149 + 33507751 = 33507900
157 + 33507743 = 33507900

Showing the first eight; more decompositions exist.
