Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531998, here are decompositions:

7 + 33531991 = 33531998
67 + 33531931 = 33531998
79 + 33531919 = 33531998
109 + 33531889 = 33531998
151 + 33531847 = 33531998
337 + 33531661 = 33531998
421 + 33531577 = 33531998
439 + 33531559 = 33531998

Showing the first eight; more decompositions exist.
