Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557620, here are decompositions:

3 + 33557617 = 33557620
17 + 33557603 = 33557620
23 + 33557597 = 33557620
53 + 33557567 = 33557620
59 + 33557561 = 33557620
149 + 33557471 = 33557620
167 + 33557453 = 33557620
191 + 33557429 = 33557620

Showing the first eight; more decompositions exist.
