Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557900, here are decompositions:

7 + 33557893 = 33557900
73 + 33557827 = 33557900
151 + 33557749 = 33557900
163 + 33557737 = 33557900
193 + 33557707 = 33557900
199 + 33557701 = 33557900
283 + 33557617 = 33557900
379 + 33557521 = 33557900

Showing the first eight; more decompositions exist.
