Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513642, here are decompositions:

11 + 33513631 = 33513642
13 + 33513629 = 33513642
31 + 33513611 = 33513642
61 + 33513581 = 33513642
73 + 33513569 = 33513642
83 + 33513559 = 33513642
101 + 33513541 = 33513642
103 + 33513539 = 33513642

Showing the first eight; more decompositions exist.
