Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533420, here are decompositions:

13 + 33533407 = 33533420
79 + 33533341 = 33533420
103 + 33533317 = 33533420
127 + 33533293 = 33533420
139 + 33533281 = 33533420
163 + 33533257 = 33533420
181 + 33533239 = 33533420
199 + 33533221 = 33533420

Showing the first eight; more decompositions exist.
