Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572166, here are decompositions:

83 + 33572083 = 33572166
137 + 33572029 = 33572166
139 + 33572027 = 33572166
157 + 33572009 = 33572166
223 + 33571943 = 33572166
227 + 33571939 = 33572166
233 + 33571933 = 33572166
293 + 33571873 = 33572166

Showing the first eight; more decompositions exist.
