Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505986, here are decompositions:

5 + 33505981 = 33505986
47 + 33505939 = 33505986
79 + 33505907 = 33505986
83 + 33505903 = 33505986
97 + 33505889 = 33505986
103 + 33505883 = 33505986
127 + 33505859 = 33505986
139 + 33505847 = 33505986

Showing the first eight; more decompositions exist.
