Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508138, here are decompositions:

11 + 33508127 = 33508138
29 + 33508109 = 33508138
47 + 33508091 = 33508138
71 + 33508067 = 33508138
149 + 33507989 = 33508138
227 + 33507911 = 33508138
239 + 33507899 = 33508138
317 + 33507821 = 33508138

Showing the first eight; more decompositions exist.
