Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581728, here are decompositions:

41 + 33581687 = 33581728
107 + 33581621 = 33581728
317 + 33581411 = 33581728
347 + 33581381 = 33581728
431 + 33581297 = 33581728
449 + 33581279 = 33581728
461 + 33581267 = 33581728
641 + 33581087 = 33581728

Showing the first eight; more decompositions exist.
