Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531992, here are decompositions:

3 + 33531989 = 33531992
61 + 33531931 = 33531992
73 + 33531919 = 33531992
79 + 33531913 = 33531992
103 + 33531889 = 33531992
139 + 33531853 = 33531992
199 + 33531793 = 33531992
211 + 33531781 = 33531992

Showing the first eight; more decompositions exist.
