Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561616, here are decompositions:

5 + 33561611 = 33561616
17 + 33561599 = 33561616
59 + 33561557 = 33561616
83 + 33561533 = 33561616
89 + 33561527 = 33561616
113 + 33561503 = 33561616
227 + 33561389 = 33561616
353 + 33561263 = 33561616

Showing the first eight; more decompositions exist.
