Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531984, here are decompositions:

7 + 33531977 = 33531984
37 + 33531947 = 33531984
53 + 33531931 = 33531984
61 + 33531923 = 33531984
71 + 33531913 = 33531984
97 + 33531887 = 33531984
107 + 33531877 = 33531984
131 + 33531853 = 33531984

Showing the first eight; more decompositions exist.
