Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508878, here are decompositions:

19 + 33508859 = 33508878
31 + 33508847 = 33508878
47 + 33508831 = 33508878
61 + 33508817 = 33508878
71 + 33508807 = 33508878
97 + 33508781 = 33508878
149 + 33508729 = 33508878
157 + 33508721 = 33508878

Showing the first eight; more decompositions exist.
