Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561828, here are decompositions:

11 + 33561817 = 33561828
29 + 33561799 = 33561828
59 + 33561769 = 33561828
61 + 33561767 = 33561828
109 + 33561719 = 33561828
149 + 33561679 = 33561828
229 + 33561599 = 33561828
257 + 33561571 = 33561828

Showing the first eight; more decompositions exist.
