Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561564, here are decompositions:

5 + 33561559 = 33561564
7 + 33561557 = 33561564
13 + 33561551 = 33561564
31 + 33561533 = 33561564
37 + 33561527 = 33561564
61 + 33561503 = 33561564
151 + 33561413 = 33561564
277 + 33561287 = 33561564

Showing the first eight; more decompositions exist.
