Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33533878, here are decompositions:

5 + 33533873 = 33533878
11 + 33533867 = 33533878
17 + 33533861 = 33533878
41 + 33533837 = 33533878
71 + 33533807 = 33533878
167 + 33533711 = 33533878
431 + 33533447 = 33533878
491 + 33533387 = 33533878

Showing the first eight; more decompositions exist.
