Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495440, here are decompositions:

3 + 495437 = 495440
7 + 495433 = 495440
19 + 495421 = 495440
79 + 495361 = 495440
97 + 495343 = 495440
103 + 495337 = 495440
139 + 495301 = 495440
151 + 495289 = 495440

Showing the first eight; more decompositions exist.
