Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33519620, here are decompositions:

3 + 33519617 = 33519620
31 + 33519589 = 33519620
37 + 33519583 = 33519620
61 + 33519559 = 33519620
73 + 33519547 = 33519620
97 + 33519523 = 33519620
163 + 33519457 = 33519620
223 + 33519397 = 33519620

Showing the first eight; more decompositions exist.
