Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89440, here are decompositions:

23 + 89417 = 89440
41 + 89399 = 89440
47 + 89393 = 89440
53 + 89387 = 89440
59 + 89381 = 89440
137 + 89303 = 89440
167 + 89273 = 89440
179 + 89261 = 89440

Showing the first eight; more decompositions exist.
