Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531900, here are decompositions:

11 + 33531889 = 33531900
13 + 33531887 = 33531900
23 + 33531877 = 33531900
47 + 33531853 = 33531900
53 + 33531847 = 33531900
107 + 33531793 = 33531900
109 + 33531791 = 33531900
151 + 33531749 = 33531900

Showing the first eight; more decompositions exist.
