Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45440, here are decompositions:

7 + 45433 = 45440
13 + 45427 = 45440
37 + 45403 = 45440
79 + 45361 = 45440
97 + 45343 = 45440
103 + 45337 = 45440
151 + 45289 = 45440
181 + 45259 = 45440

Showing the first eight; more decompositions exist.
