Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612220, here are decompositions:

3 + 33612217 = 33612220
17 + 33612203 = 33612220
167 + 33612053 = 33612220
179 + 33612041 = 33612220
233 + 33611987 = 33612220
269 + 33611951 = 33612220
293 + 33611927 = 33612220
599 + 33611621 = 33612220

Showing the first eight; more decompositions exist.
