Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515538, here are decompositions:

19 + 33515519 = 33515538
29 + 33515509 = 33515538
37 + 33515501 = 33515538
101 + 33515437 = 33515538
107 + 33515431 = 33515538
179 + 33515359 = 33515538
181 + 33515357 = 33515538
197 + 33515341 = 33515538

Showing the first eight; more decompositions exist.
