Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557664, here are decompositions:

37 + 33557627 = 33557664
47 + 33557617 = 33557664
61 + 33557603 = 33557664
67 + 33557597 = 33557664
97 + 33557567 = 33557664
103 + 33557561 = 33557664
193 + 33557471 = 33557664
197 + 33557467 = 33557664

Showing the first eight; more decompositions exist.
