Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601872, here are decompositions:

23 + 33601849 = 33601872
41 + 33601831 = 33601872
53 + 33601819 = 33601872
61 + 33601811 = 33601872
71 + 33601801 = 33601872
103 + 33601769 = 33601872
149 + 33601723 = 33601872
179 + 33601693 = 33601872

Showing the first eight; more decompositions exist.
