Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591440, here are decompositions:

13 + 33591427 = 33591440
31 + 33591409 = 33591440
37 + 33591403 = 33591440
97 + 33591343 = 33591440
151 + 33591289 = 33591440
163 + 33591277 = 33591440
241 + 33591199 = 33591440
373 + 33591067 = 33591440

Showing the first eight; more decompositions exist.
