Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513820, here are decompositions:

23 + 33513797 = 33513820
59 + 33513761 = 33513820
89 + 33513731 = 33513820
107 + 33513713 = 33513820
113 + 33513707 = 33513820
191 + 33513629 = 33513820
239 + 33513581 = 33513820
251 + 33513569 = 33513820

Showing the first eight; more decompositions exist.
