Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512920, here are decompositions:

47 + 33512873 = 33512920
83 + 33512837 = 33512920
113 + 33512807 = 33512920
137 + 33512783 = 33512920
167 + 33512753 = 33512920
173 + 33512747 = 33512920
197 + 33512723 = 33512920
239 + 33512681 = 33512920

Showing the first eight; more decompositions exist.
