Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571980, here are decompositions:

17 + 33571963 = 33571980
37 + 33571943 = 33571980
41 + 33571939 = 33571980
47 + 33571933 = 33571980
107 + 33571873 = 33571980
131 + 33571849 = 33571980
149 + 33571831 = 33571980
151 + 33571829 = 33571980

Showing the first eight; more decompositions exist.
