Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561994, here are decompositions:

17 + 33561977 = 33561994
41 + 33561953 = 33561994
83 + 33561911 = 33561994
113 + 33561881 = 33561994
227 + 33561767 = 33561994
251 + 33561743 = 33561994
353 + 33561641 = 33561994
383 + 33561611 = 33561994

Showing the first eight; more decompositions exist.
