Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601878, here are decompositions:

29 + 33601849 = 33601878
47 + 33601831 = 33601878
59 + 33601819 = 33601878
61 + 33601817 = 33601878
67 + 33601811 = 33601878
109 + 33601769 = 33601878
181 + 33601697 = 33601878
199 + 33601679 = 33601878

Showing the first eight; more decompositions exist.
