Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606220, here are decompositions:

17 + 33606203 = 33606220
29 + 33606191 = 33606220
41 + 33606179 = 33606220
47 + 33606173 = 33606220
71 + 33606149 = 33606220
83 + 33606137 = 33606220
107 + 33606113 = 33606220
149 + 33606071 = 33606220

Showing the first eight; more decompositions exist.
