Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33525920, here are decompositions:

3 + 33525917 = 33525920
19 + 33525901 = 33525920
31 + 33525889 = 33525920
37 + 33525883 = 33525920
61 + 33525859 = 33525920
163 + 33525757 = 33525920
193 + 33525727 = 33525920
229 + 33525691 = 33525920

Showing the first eight; more decompositions exist.
