Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581620, here are decompositions:

3 + 33581617 = 33581620
47 + 33581573 = 33581620
179 + 33581441 = 33581620
227 + 33581393 = 33581620
239 + 33581381 = 33581620
269 + 33581351 = 33581620
353 + 33581267 = 33581620
503 + 33581117 = 33581620

Showing the first eight; more decompositions exist.
