Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561940, here are decompositions:

11 + 33561929 = 33561940
23 + 33561917 = 33561940
29 + 33561911 = 33561940
59 + 33561881 = 33561940
89 + 33561851 = 33561940
101 + 33561839 = 33561940
173 + 33561767 = 33561940
197 + 33561743 = 33561940

Showing the first eight; more decompositions exist.
