Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505664, here are decompositions:

43 + 33505621 = 33505664
97 + 33505567 = 33505664
223 + 33505441 = 33505664
271 + 33505393 = 33505664
487 + 33505177 = 33505664
541 + 33505123 = 33505664
547 + 33505117 = 33505664
607 + 33505057 = 33505664

Showing the first eight; more decompositions exist.
