Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495378, here are decompositions:

7 + 495371 = 495378
17 + 495361 = 495378
19 + 495359 = 495378
31 + 495347 = 495378
41 + 495337 = 495378
71 + 495307 = 495378
89 + 495289 = 495378
101 + 495277 = 495378

Showing the first eight; more decompositions exist.
