Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581644, here are decompositions:

23 + 33581621 = 33581644
71 + 33581573 = 33581644
233 + 33581411 = 33581644
251 + 33581393 = 33581644
263 + 33581381 = 33581644
293 + 33581351 = 33581644
347 + 33581297 = 33581644
353 + 33581291 = 33581644

Showing the first eight; more decompositions exist.
