Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33571986, here are decompositions:

23 + 33571963 = 33571986
43 + 33571943 = 33571986
47 + 33571939 = 33571986
53 + 33571933 = 33571986
113 + 33571873 = 33571986
137 + 33571849 = 33571986
157 + 33571829 = 33571986
163 + 33571823 = 33571986

Showing the first eight; more decompositions exist.
