Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557668, here are decompositions:

5 + 33557663 = 33557668
41 + 33557627 = 33557668
71 + 33557597 = 33557668
101 + 33557567 = 33557668
107 + 33557561 = 33557668
197 + 33557471 = 33557668
239 + 33557429 = 33557668
251 + 33557417 = 33557668

Showing the first eight; more decompositions exist.
