Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538320, here are decompositions:

7 + 33538313 = 33538320
17 + 33538303 = 33538320
47 + 33538273 = 33538320
61 + 33538259 = 33538320
73 + 33538247 = 33538320
89 + 33538231 = 33538320
97 + 33538223 = 33538320
103 + 33538217 = 33538320

Showing the first eight; more decompositions exist.
