Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545620, here are decompositions:

11 + 33545609 = 33545620
23 + 33545597 = 33545620
29 + 33545591 = 33545620
41 + 33545579 = 33545620
137 + 33545483 = 33545620
191 + 33545429 = 33545620
197 + 33545423 = 33545620
239 + 33545381 = 33545620

Showing the first eight; more decompositions exist.
