Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512980, here are decompositions:

3 + 33512977 = 33512980
41 + 33512939 = 33512980
107 + 33512873 = 33512980
173 + 33512807 = 33512980
197 + 33512783 = 33512980
227 + 33512753 = 33512980
233 + 33512747 = 33512980
257 + 33512723 = 33512980

Showing the first eight; more decompositions exist.
