Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561664, here are decompositions:

11 + 33561653 = 33561664
23 + 33561641 = 33561664
53 + 33561611 = 33561664
107 + 33561557 = 33561664
113 + 33561551 = 33561664
131 + 33561533 = 33561664
137 + 33561527 = 33561664
251 + 33561413 = 33561664

Showing the first eight; more decompositions exist.
