Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555828, here are decompositions:

11 + 33555817 = 33555828
29 + 33555799 = 33555828
71 + 33555757 = 33555828
101 + 33555727 = 33555828
127 + 33555701 = 33555828
149 + 33555679 = 33555828
167 + 33555661 = 33555828
181 + 33555647 = 33555828

Showing the first eight; more decompositions exist.
