Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561894, here are decompositions:

13 + 33561881 = 33561894
17 + 33561877 = 33561894
43 + 33561851 = 33561894
127 + 33561767 = 33561894
151 + 33561743 = 33561894
241 + 33561653 = 33561894
283 + 33561611 = 33561894
337 + 33561557 = 33561894

Showing the first eight; more decompositions exist.
