Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609808, here are decompositions:

47 + 33609761 = 33609808
59 + 33609749 = 33609808
107 + 33609701 = 33609808
137 + 33609671 = 33609808
227 + 33609581 = 33609808
269 + 33609539 = 33609808
431 + 33609377 = 33609808
521 + 33609287 = 33609808

Showing the first eight; more decompositions exist.
