Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557990, here are decompositions:

3 + 33557987 = 33557990
73 + 33557917 = 33557990
79 + 33557911 = 33557990
97 + 33557893 = 33557990
163 + 33557827 = 33557990
181 + 33557809 = 33557990
223 + 33557767 = 33557990
241 + 33557749 = 33557990

Showing the first eight; more decompositions exist.
