Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 35440, here are decompositions:

3 + 35437 = 35440
17 + 35423 = 35440
47 + 35393 = 35440
59 + 35381 = 35440
101 + 35339 = 35440
113 + 35327 = 35440
149 + 35291 = 35440
173 + 35267 = 35440

Showing the first eight; more decompositions exist.
