Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557574, here are decompositions:

7 + 33557567 = 33557574
13 + 33557561 = 33557574
31 + 33557543 = 33557574
53 + 33557521 = 33557574
103 + 33557471 = 33557574
107 + 33557467 = 33557574
151 + 33557423 = 33557574
157 + 33557417 = 33557574

Showing the first eight; more decompositions exist.
