Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605780, here are decompositions:

31 + 33605749 = 33605780
67 + 33605713 = 33605780
79 + 33605701 = 33605780
97 + 33605683 = 33605780
337 + 33605443 = 33605780
487 + 33605293 = 33605780
631 + 33605149 = 33605780
643 + 33605137 = 33605780

Showing the first eight; more decompositions exist.
