Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17440, here are decompositions:

23 + 17417 = 17440
47 + 17393 = 17440
53 + 17387 = 17440
89 + 17351 = 17440
107 + 17333 = 17440
113 + 17327 = 17440
149 + 17291 = 17440
233 + 17207 = 17440

Showing the first eight; more decompositions exist.
