Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489640, here are decompositions:

11 + 33489629 = 33489640
17 + 33489623 = 33489640
29 + 33489611 = 33489640
47 + 33489593 = 33489640
71 + 33489569 = 33489640
137 + 33489503 = 33489640
263 + 33489377 = 33489640
347 + 33489293 = 33489640

Showing the first eight; more decompositions exist.
