Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557628, here are decompositions:

11 + 33557617 = 33557628
31 + 33557597 = 33557628
61 + 33557567 = 33557628
67 + 33557561 = 33557628
107 + 33557521 = 33557628
157 + 33557471 = 33557628
199 + 33557429 = 33557628
211 + 33557417 = 33557628

Showing the first eight; more decompositions exist.
