Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557680, here are decompositions:

17 + 33557663 = 33557680
53 + 33557627 = 33557680
83 + 33557597 = 33557680
113 + 33557567 = 33557680
137 + 33557543 = 33557680
227 + 33557453 = 33557680
251 + 33557429 = 33557680
257 + 33557423 = 33557680

Showing the first eight; more decompositions exist.
