Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505472, here are decompositions:

31 + 33505441 = 33505472
79 + 33505393 = 33505472
109 + 33505363 = 33505472
163 + 33505309 = 33505472
211 + 33505261 = 33505472
349 + 33505123 = 33505472
421 + 33505051 = 33505472
433 + 33505039 = 33505472

Showing the first eight; more decompositions exist.
