Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605916, here are decompositions:

53 + 33605863 = 33605916
67 + 33605849 = 33605916
73 + 33605843 = 33605916
79 + 33605837 = 33605916
109 + 33605807 = 33605916
167 + 33605749 = 33605916
193 + 33605723 = 33605916
199 + 33605717 = 33605916

Showing the first eight; more decompositions exist.
