Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33535390, here are decompositions:

47 + 33535343 = 33535390
71 + 33535319 = 33535390
113 + 33535277 = 33535390
149 + 33535241 = 33535390
197 + 33535193 = 33535390
227 + 33535163 = 33535390
233 + 33535157 = 33535390
359 + 33535031 = 33535390

Showing the first eight; more decompositions exist.
