Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538220, here are decompositions:

3 + 33538217 = 33538220
13 + 33538207 = 33538220
61 + 33538159 = 33538220
139 + 33538081 = 33538220
151 + 33538069 = 33538220
193 + 33538027 = 33538220
211 + 33538009 = 33538220
607 + 33537613 = 33538220

Showing the first eight; more decompositions exist.
