Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531940, here are decompositions:

11 + 33531929 = 33531940
17 + 33531923 = 33531940
53 + 33531887 = 33531940
149 + 33531791 = 33531940
191 + 33531749 = 33531940
269 + 33531671 = 33531940
353 + 33531587 = 33531940
461 + 33531479 = 33531940

Showing the first eight; more decompositions exist.
