Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557648, here are decompositions:

31 + 33557617 = 33557648
127 + 33557521 = 33557648
139 + 33557509 = 33557648
181 + 33557467 = 33557648
307 + 33557341 = 33557648
331 + 33557317 = 33557648
547 + 33557101 = 33557648
571 + 33557077 = 33557648

Showing the first eight; more decompositions exist.
