Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478432, here are decompositions:

11 + 33478421 = 33478432
41 + 33478391 = 33478432
101 + 33478331 = 33478432
149 + 33478283 = 33478432
233 + 33478199 = 33478432
263 + 33478169 = 33478432
269 + 33478163 = 33478432
311 + 33478121 = 33478432

Showing the first eight; more decompositions exist.
