Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500988, here are decompositions:

5 + 33500983 = 33500988
7 + 33500981 = 33500988
19 + 33500969 = 33500988
61 + 33500927 = 33500988
67 + 33500921 = 33500988
71 + 33500917 = 33500988
97 + 33500891 = 33500988
109 + 33500879 = 33500988

Showing the first eight; more decompositions exist.
