Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32440, here are decompositions:

11 + 32429 = 32440
17 + 32423 = 32440
29 + 32411 = 32440
59 + 32381 = 32440
71 + 32369 = 32440
113 + 32327 = 32440
131 + 32309 = 32440
137 + 32303 = 32440

Showing the first eight; more decompositions exist.
