Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605878, here are decompositions:

29 + 33605849 = 33605878
41 + 33605837 = 33605878
71 + 33605807 = 33605878
149 + 33605729 = 33605878
311 + 33605567 = 33605878
347 + 33605531 = 33605878
461 + 33605417 = 33605878
491 + 33605387 = 33605878

Showing the first eight; more decompositions exist.
