Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543666, here are decompositions:

5 + 33543661 = 33543666
17 + 33543649 = 33543666
83 + 33543583 = 33543666
89 + 33543577 = 33543666
113 + 33543553 = 33543666
127 + 33543539 = 33543666
137 + 33543529 = 33543666
157 + 33543509 = 33543666

Showing the first eight; more decompositions exist.
