Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572172, here are decompositions:

31 + 33572141 = 33572172
41 + 33572131 = 33572172
89 + 33572083 = 33572172
131 + 33572041 = 33572172
163 + 33572009 = 33572172
229 + 33571943 = 33572172
233 + 33571939 = 33572172
239 + 33571933 = 33572172

Showing the first eight; more decompositions exist.
