Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33505820, here are decompositions:

31 + 33505789 = 33505820
43 + 33505777 = 33505820
97 + 33505723 = 33505820
157 + 33505663 = 33505820
199 + 33505621 = 33505820
241 + 33505579 = 33505820
277 + 33505543 = 33505820
373 + 33505447 = 33505820

Showing the first eight; more decompositions exist.
