Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493220, here are decompositions:

3 + 33493217 = 33493220
37 + 33493183 = 33493220
67 + 33493153 = 33493220
139 + 33493081 = 33493220
157 + 33493063 = 33493220
223 + 33492997 = 33493220
331 + 33492889 = 33493220
349 + 33492871 = 33493220

Showing the first eight; more decompositions exist.
