Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508128, here are decompositions:

19 + 33508109 = 33508128
37 + 33508091 = 33508128
61 + 33508067 = 33508128
109 + 33508019 = 33508128
139 + 33507989 = 33508128
191 + 33507937 = 33508128
229 + 33507899 = 33508128
239 + 33507889 = 33508128

Showing the first eight; more decompositions exist.
