Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561620, here are decompositions:

13 + 33561607 = 33561620
61 + 33561559 = 33561620
151 + 33561469 = 33561620
241 + 33561379 = 33561620
277 + 33561343 = 33561620
349 + 33561271 = 33561620
439 + 33561181 = 33561620
541 + 33561079 = 33561620

Showing the first eight; more decompositions exist.
