Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591372, here are decompositions:

29 + 33591343 = 33591372
43 + 33591329 = 33591372
83 + 33591289 = 33591372
149 + 33591223 = 33591372
173 + 33591199 = 33591372
211 + 33591161 = 33591372
233 + 33591139 = 33591372
271 + 33591101 = 33591372

Showing the first eight; more decompositions exist.
