Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508986, here are decompositions:

13 + 33508973 = 33508986
67 + 33508919 = 33508986
83 + 33508903 = 33508986
89 + 33508897 = 33508986
127 + 33508859 = 33508986
139 + 33508847 = 33508986
157 + 33508829 = 33508986
179 + 33508807 = 33508986

Showing the first eight; more decompositions exist.
