Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533840, here are decompositions:

3 + 33533837 = 33533840
19 + 33533821 = 33533840
61 + 33533779 = 33533840
79 + 33533761 = 33533840
181 + 33533659 = 33533840
199 + 33533641 = 33533840
313 + 33533527 = 33533840
349 + 33533491 = 33533840

Showing the first eight; more decompositions exist.
