Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508930, here are decompositions:

11 + 33508919 = 33508930
29 + 33508901 = 33508930
71 + 33508859 = 33508930
83 + 33508847 = 33508930
101 + 33508829 = 33508930
113 + 33508817 = 33508930
149 + 33508781 = 33508930
197 + 33508733 = 33508930

Showing the first eight; more decompositions exist.
