Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533220, here are decompositions:

37 + 33533183 = 33533220
47 + 33533173 = 33533220
53 + 33533167 = 33533220
59 + 33533161 = 33533220
79 + 33533141 = 33533220
137 + 33533083 = 33533220
191 + 33533029 = 33533220
199 + 33533021 = 33533220

Showing the first eight; more decompositions exist.
