Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503680, here are decompositions:

3 + 33503677 = 33503680
47 + 33503633 = 33503680
53 + 33503627 = 33503680
107 + 33503573 = 33503680
137 + 33503543 = 33503680
227 + 33503453 = 33503680
251 + 33503429 = 33503680
269 + 33503411 = 33503680

Showing the first eight; more decompositions exist.
