Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523878, here are decompositions:

41 + 33523837 = 33523878
79 + 33523799 = 33523878
97 + 33523781 = 33523878
109 + 33523769 = 33523878
127 + 33523751 = 33523878
151 + 33523727 = 33523878
181 + 33523697 = 33523878
277 + 33523601 = 33523878

Showing the first eight; more decompositions exist.
