Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505988, here are decompositions:

7 + 33505981 = 33505988
37 + 33505951 = 33505988
199 + 33505789 = 33505988
211 + 33505777 = 33505988
367 + 33505621 = 33505988
409 + 33505579 = 33505988
421 + 33505567 = 33505988
541 + 33505447 = 33505988

Showing the first eight; more decompositions exist.
