Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505990, here are decompositions:

29 + 33505961 = 33505990
83 + 33505907 = 33505990
101 + 33505889 = 33505990
107 + 33505883 = 33505990
131 + 33505859 = 33505990
137 + 33505853 = 33505990
191 + 33505799 = 33505990
239 + 33505751 = 33505990

Showing the first eight; more decompositions exist.
