Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538666, here are decompositions:

3 + 33538663 = 33538666
17 + 33538649 = 33538666
23 + 33538643 = 33538666
47 + 33538619 = 33538666
149 + 33538517 = 33538666
167 + 33538499 = 33538666
197 + 33538469 = 33538666
263 + 33538403 = 33538666

Showing the first eight; more decompositions exist.
