Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523872, here are decompositions:

29 + 33523843 = 33523872
43 + 33523829 = 33523872
73 + 33523799 = 33523872
79 + 33523793 = 33523872
103 + 33523769 = 33523872
113 + 33523759 = 33523872
149 + 33523723 = 33523872
271 + 33523601 = 33523872

Showing the first eight; more decompositions exist.
