Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557644, here are decompositions:

17 + 33557627 = 33557644
41 + 33557603 = 33557644
47 + 33557597 = 33557644
83 + 33557561 = 33557644
101 + 33557543 = 33557644
173 + 33557471 = 33557644
191 + 33557453 = 33557644
227 + 33557417 = 33557644

Showing the first eight; more decompositions exist.
