Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538266, here are decompositions:

7 + 33538259 = 33538266
19 + 33538247 = 33538266
43 + 33538223 = 33538266
59 + 33538207 = 33538266
107 + 33538159 = 33538266
137 + 33538129 = 33538266
163 + 33538103 = 33538266
197 + 33538069 = 33538266

Showing the first eight; more decompositions exist.
