Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621798, here are decompositions:

11 + 33621787 = 33621798
17 + 33621781 = 33621798
37 + 33621761 = 33621798
47 + 33621751 = 33621798
71 + 33621727 = 33621798
107 + 33621691 = 33621798
137 + 33621661 = 33621798
149 + 33621649 = 33621798

Showing the first eight; more decompositions exist.
