Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33512890, here are decompositions:

17 + 33512873 = 33512890
53 + 33512837 = 33512890
83 + 33512807 = 33512890
107 + 33512783 = 33512890
137 + 33512753 = 33512890
167 + 33512723 = 33512890
311 + 33512579 = 33512890
317 + 33512573 = 33512890

Showing the first eight; more decompositions exist.
