Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609680, here are decompositions:

31 + 33609649 = 33609680
73 + 33609607 = 33609680
109 + 33609571 = 33609680
151 + 33609529 = 33609680
199 + 33609481 = 33609680
277 + 33609403 = 33609680
331 + 33609349 = 33609680
367 + 33609313 = 33609680

Showing the first eight; more decompositions exist.
