Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515220, here are decompositions:

17 + 33515203 = 33515220
61 + 33515159 = 33515220
163 + 33515057 = 33515220
199 + 33515021 = 33515220
251 + 33514969 = 33515220
293 + 33514927 = 33515220
313 + 33514907 = 33515220
353 + 33514867 = 33515220

Showing the first eight; more decompositions exist.
