Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561666, here are decompositions:

13 + 33561653 = 33561666
59 + 33561607 = 33561666
67 + 33561599 = 33561666
107 + 33561559 = 33561666
109 + 33561557 = 33561666
139 + 33561527 = 33561666
163 + 33561503 = 33561666
197 + 33561469 = 33561666

Showing the first eight; more decompositions exist.
