Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557816, here are decompositions:

7 + 33557809 = 33557816
67 + 33557749 = 33557816
79 + 33557737 = 33557816
109 + 33557707 = 33557816
199 + 33557617 = 33557816
307 + 33557509 = 33557816
349 + 33557467 = 33557816
499 + 33557317 = 33557816

Showing the first eight; more decompositions exist.
