Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561556, here are decompositions:

5 + 33561551 = 33561556
23 + 33561533 = 33561556
29 + 33561527 = 33561556
53 + 33561503 = 33561556
167 + 33561389 = 33561556
269 + 33561287 = 33561556
293 + 33561263 = 33561556
359 + 33561197 = 33561556

Showing the first eight; more decompositions exist.
