Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555220, here are decompositions:

3 + 33555217 = 33555220
11 + 33555209 = 33555220
29 + 33555191 = 33555220
53 + 33555167 = 33555220
71 + 33555149 = 33555220
89 + 33555131 = 33555220
131 + 33555089 = 33555220
227 + 33554993 = 33555220

Showing the first eight; more decompositions exist.
