Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508218, here are decompositions:

5 + 33508213 = 33508218
59 + 33508159 = 33508218
71 + 33508147 = 33508218
109 + 33508109 = 33508218
127 + 33508091 = 33508218
151 + 33508067 = 33508218
199 + 33508019 = 33508218
229 + 33507989 = 33508218

Showing the first eight; more decompositions exist.
