Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33240, here are decompositions:

17 + 33223 = 33240
29 + 33211 = 33240
37 + 33203 = 33240
41 + 33199 = 33240
59 + 33181 = 33240
61 + 33179 = 33240
79 + 33161 = 33240
89 + 33151 = 33240

Showing the first eight; more decompositions exist.
