Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572900, here are decompositions:

3 + 33572897 = 33572900
19 + 33572881 = 33572900
37 + 33572863 = 33572900
43 + 33572857 = 33572900
73 + 33572827 = 33572900
157 + 33572743 = 33572900
199 + 33572701 = 33572900
271 + 33572629 = 33572900

Showing the first eight; more decompositions exist.
