Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525900, here are decompositions:

11 + 33525889 = 33525900
17 + 33525883 = 33525900
29 + 33525871 = 33525900
41 + 33525859 = 33525900
97 + 33525803 = 33525900
127 + 33525773 = 33525900
173 + 33525727 = 33525900
193 + 33525707 = 33525900

Showing the first eight; more decompositions exist.
