Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539440, here are decompositions:

47 + 33539393 = 33539440
83 + 33539357 = 33539440
107 + 33539333 = 33539440
131 + 33539309 = 33539440
149 + 33539291 = 33539440
197 + 33539243 = 33539440
239 + 33539201 = 33539440
281 + 33539159 = 33539440

Showing the first eight; more decompositions exist.
