Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33565440, here are decompositions:

67 + 33565373 = 33565440
71 + 33565369 = 33565440
101 + 33565339 = 33565440
107 + 33565333 = 33565440
127 + 33565313 = 33565440
241 + 33565199 = 33565440
263 + 33565177 = 33565440
269 + 33565171 = 33565440

Showing the first eight; more decompositions exist.
