Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531920, here are decompositions:

7 + 33531913 = 33531920
31 + 33531889 = 33531920
43 + 33531877 = 33531920
67 + 33531853 = 33531920
73 + 33531847 = 33531920
127 + 33531793 = 33531920
139 + 33531781 = 33531920
241 + 33531679 = 33531920

Showing the first eight; more decompositions exist.
