Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533820, here are decompositions:

13 + 33533807 = 33533820
41 + 33533779 = 33533820
59 + 33533761 = 33533820
71 + 33533749 = 33533820
101 + 33533719 = 33533820
109 + 33533711 = 33533820
157 + 33533663 = 33533820
179 + 33533641 = 33533820

Showing the first eight; more decompositions exist.
