Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623220, here are decompositions:

19 + 33623201 = 33623220
47 + 33623173 = 33623220
53 + 33623167 = 33623220
61 + 33623159 = 33623220
67 + 33623153 = 33623220
83 + 33623137 = 33623220
131 + 33623089 = 33623220
149 + 33623071 = 33623220

Showing the first eight; more decompositions exist.
