Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33522138, here are decompositions:

11 + 33522127 = 33522138
17 + 33522121 = 33522138
37 + 33522101 = 33522138
79 + 33522059 = 33522138
149 + 33521989 = 33522138
157 + 33521981 = 33522138
179 + 33521959 = 33522138
211 + 33521927 = 33522138

Showing the first eight; more decompositions exist.
