Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33040, here are decompositions:

3 + 33037 = 33040
11 + 33029 = 33040
17 + 33023 = 33040
41 + 32999 = 33040
47 + 32993 = 33040
53 + 32987 = 33040
71 + 32969 = 33040
83 + 32957 = 33040

Showing the first eight; more decompositions exist.
