Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612808, here are decompositions:

11 + 33612797 = 33612808
101 + 33612707 = 33612808
107 + 33612701 = 33612808
137 + 33612671 = 33612808
197 + 33612611 = 33612808
227 + 33612581 = 33612808
479 + 33612329 = 33612808
569 + 33612239 = 33612808

Showing the first eight; more decompositions exist.
