Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561978, here are decompositions:

19 + 33561959 = 33561978
29 + 33561949 = 33561978
59 + 33561919 = 33561978
61 + 33561917 = 33561978
67 + 33561911 = 33561978
97 + 33561881 = 33561978
101 + 33561877 = 33561978
127 + 33561851 = 33561978

Showing the first eight; more decompositions exist.
