Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561808, here are decompositions:

29 + 33561779 = 33561808
41 + 33561767 = 33561808
89 + 33561719 = 33561808
167 + 33561641 = 33561808
197 + 33561611 = 33561808
251 + 33561557 = 33561808
257 + 33561551 = 33561808
281 + 33561527 = 33561808

Showing the first eight; more decompositions exist.
