Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509372, here are decompositions:

19 + 33509353 = 33509372
103 + 33509269 = 33509372
163 + 33509209 = 33509372
199 + 33509173 = 33509372
223 + 33509149 = 33509372
229 + 33509143 = 33509372
331 + 33509041 = 33509372
541 + 33508831 = 33509372

Showing the first eight; more decompositions exist.
